ARM: tegra: Reserve 32MB for the Linux kernel

Booting recently Linux -next kernels on 32-bit Tegra devices has been
failing when using the 'multi_v7_defconfig' kenrel configuration because
the size of has grown such that it is overwriting the FDT blob.

Current Linux -next kernels built with the 'multi_v7_defconfig' have a
total size of ~19.5MB (where .text is ~12.5MB, .data is ~6.5MB and .bss
is ~0.5MB). Therefore, increase the memory location reserved for the
Linux kernel to 32MB from 16MB for 32-bit Tegra devices.

This change has been boot tested on Tegra20 Ventana, Tegra30 Cardhu and
Tegra124 Jetson TK1 with the Linux next tree (20190212).

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

ARM: Move SYS_CACHELINE_SIZE over to Kconfig

This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all
cases we are mirroring the values used by the Linux Kernel here. Also,
so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

ARM: tegra: expand all SPL sizes to be consistent

The size allocation for SPL is increased in all cases to match the
already-expanded value used on Tegra124. This is both for general
consistency, and because the seaboard build trips over the limit already
when using one of the ARM compilers packaged with 14.04. For the record,
when building Seaboard:

arm-linux-gnueabi- SPL is too big by 0x36 bytes
arm-linux-gnueabihf- SPL fits by 0x2a bytes
arm-none-eabi- SPL fits by 0xa bytes

(Those figures are from builds with the expanded SPL size allocation,
relative to the non-expanded SPL size limit; they're better by about
6 bytes in the more constrained build.)

ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalization

As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.

The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.

I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.

The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

mmc: tegra: use bounce buffer APIs

Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In
some cases (e.g. user load commands) this cannot be guaranteed by callers
of the MMC APIs. To solve this, modify the Tegra MMC driver to use the
new bounce_buffer_*() APIs.

Note: Ideally, all U-Boot code will always provide address- and size-
aligned buffers, so a bounce buffer will only ever be needed for user-
supplied buffers (e.g. load commands). Ensuring this removes the need
for performance-sucking bounce buffer cache management and memcpy()s.
The one known exception at present is the SCR buffer in sd_change_freq(),
which is only 8 bytes long. Solving this requires enhancing struct
mmc_data to know the difference between buffer size and transferred data
size, or forcing all callers of mmc_send_cmd() to have allocated buffers
using ALLOC_CACHE_ALIGN_BUFFER(), which while true in this case, is not
enforced in any way at present, and so cannot be assumed by the core MMC
code.

ARM: tegra: define CONFIG_SYS_BOOTMAPSZ

This define indicates the size of the memory region where it is safe
to place data passed to the Linux kernel (ATAGs, DTB, initrd). The
value needs to be:

a) Less than or equal to RAM size.
b) Small enough that the area is not within the kernel's highmem region,
since the kernel cannot access ATAGs/DTB/initrd from highmem.
c) Large enough to hold the kernel+DTB+initrd.

256M seems large enough for (c) in most circumstances, and small enough
to satisfy (a) and (b) across any possible Tegra board. Note that the
user can override this value via environment variable "bootm_mapsize"
if needed.

The advantage of defining BOOTMAPSZ is that we no longer need to define
variable fdt_high in the default environment. Previously, we defined
this to prevent the DTB from being relocated to the very end of RAM,
which on most Tegra systems is within highmem, and hence which would
cause boot failures. A user can still define this variable themselves
if they want the FDT to be either left in-place wherever loaded, or
copied to some other specific location. Similarly, there should no
longer be a strict requirement for the user to define initrd_high if
using an initrd.

the size of has grown such that it is overwriting the FDT blob.

Current Linux -next kernels built with the 'multi_v7_defconfig' have a

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all

so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

ARM: tegra: expand all SPL sizes to be consistent

The size allocation for SPL is increased in all cases to match the
already-expanded value used on Tegra124. This is both for general
consistency, and because the seaboard build trips over the limit already
when using one of the ARM compilers packaged with 14.04. For the record,
when building Seaboard:

arm-linux-gnueabi- SPL is too big by 0x36 bytes
arm-linux-gnueabihf- SPL fits by 0x2a bytes
arm-none-eabi- SPL fits by 0xa bytes

(Those figures are from builds with the expanded SPL size allocation,
relative to the non-expanded SPL size limit; they're better by about
6 bytes in the more constrained build.)

ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalization

As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.

The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.

I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.

The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

mmc: tegra: use bounce buffer APIs

Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In
some cases (e.g. user load commands) this cannot be guaranteed by callers
of the MMC APIs. To solve this, modify the Tegra MMC driver to use the
new bounce_buffer_*() APIs.

Note: Ideally, all U-Boot code will always provide address- and size-
aligned buffers, so a bounce buffer will only ever be needed for user-
supplied buffers (e.g. load commands). Ensuring this removes the need
for performance-sucking bounce buffer cache management and memcpy()s.
The one known exception at present is the SCR buffer in sd_change_freq(),
which is only 8 bytes long. Solving this requires enhancing struct
mmc_data to know the difference between buffer size and transferred data
size, or forcing all callers of mmc_send_cmd() to have allocated buffers
using ALLOC_CACHE_ALIGN_BUFFER(), which while true in this case, is not
enforced in any way at present, and so cannot be assumed by the core MMC
code.

single memory image. Hence, the maximum SPL size is the different in
TEXT_BASE for SPL and main U-Boot. Instead of manually calculating
SPL_MAX_SIZE based on those two TEXT_BASE, which can lead to errors if
one TEXT_BASE is changed without updating SPL_MAX_SIZE, simply perform
the calculation automatically.

ARM: tegra: define CONFIG_SYS_BOOTMAPSZ

This define indicates the size of the memory region where it is safe
to place data passed to the Linux kernel (ATAGs, DTB, initrd). The
value needs to be:

a) Less than or equal to RAM size.
b) Small enough that the area is not within the kernel's highmem region,
since the kernel cannot access ATAGs/DTB/initrd from highmem.
c) Large enough to hold the kernel+DTB+initrd.

256M seems large enough for (c) in most circumstances, and small enough
to satisfy (a) and (b) across any possible Tegra board. Note that the
user can override this value via environment variable "bootm_mapsize"
if needed.

The advantage of defining BOOTMAPSZ is that we no longer need to define
variable fdt_high in the default environment. Previously, we defined
this to prevent the DTB from being relocated to the very end of RAM,
which on most Tegra systems is within highmem, and hence which would
cause boot failures. A user can still define this variable themselves
if they want the FDT to be either left in-place wherever loaded, or
copied to some other specific location. Similarly, there should no
longer be a strict requirement for the user to define initrd_high if
using an initrd.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

ARM: tegra: expand all SPL sizes to be consistent

The size allocation for SPL is increased in all cases to match the
already-expanded value used on Tegra124. This is both for general
consistency, and because the seaboard build trips over the limit already
when using one of the ARM compilers packaged with 14.04. For the record,
when building Seaboard:

arm-linux-gnueabi- SPL is too big by 0x36 bytes
arm-linux-gnueabihf- SPL fits by 0x2a bytes
arm-none-eabi- SPL fits by 0xa bytes

(Those figures are from builds with the expanded SPL size allocation,
relative to the non-expanded SPL size limit; they're better by about
6 bytes in the more constrained build.)

ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalization

As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.

The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.

I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.

The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

mmc: tegra: use bounce buffer APIs

Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In
some cases (e.g. user load commands) this cannot be guaranteed by callers
of the MMC APIs. To solve this, modify the Tegra MMC driver to use the
new bounce_buffer_*() APIs.

Note: Ideally, all U-Boot code will always provide address- and size-
aligned buffers, so a bounce buffer will only ever be needed for user-
supplied buffers (e.g. load commands). Ensuring this removes the need
for performance-sucking bounce buffer cache management and memcpy()s.
The one known exception at present is the SCR buffer in sd_change_freq(),
which is only 8 bytes long. Solving this requires enhancing struct

one TEXT_BASE is changed without updating SPL_MAX_SIZE, simply perform

ARM: tegra: define CONFIG_SYS_BOOTMAPSZ

This define indicates the size of the memory region where it is safe
to place data passed to the Linux kernel (ATAGs, DTB, initrd). The
value needs to be:

a) Less than or equal to RAM size.
b) Small enough that the area is not within the kernel's highmem region,
since the kernel cannot access ATAGs/DTB/initrd from highmem.
c) Large enough to hold the kernel+DTB+initrd.

256M seems large enough for (c) in most circumstances, and small enough
to satisfy (a) and (b) across any possible Tegra board. Note that the
user can override this value via environment variable "bootm_mapsize"
if needed.

The advantage of defining BOOTMAPSZ is that we no longer need to define
variable fdt_high in the default environment. Previously, we defined
this to prevent the DTB from being relocated to the very end of RAM,
which on most Tegra systems is within highmem, and hence which would
cause boot failures. A user can still define this variable themselves
if they want the FDT to be either left in-place wherever loaded, or
copied to some other specific location. Similarly, there should no
longer be a strict requirement for the user to define initrd_high if
using an initrd.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all

so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

ARM: tegra: expand all SPL sizes to be consistent

The size allocation for SPL is increased in all cases to match the
already-expanded value used on Tegra124. This is both for general
consistency, and because the seaboard build trips over the limit already
when using one of the ARM compilers packaged with 14.04. For the record,
when building Seaboard:

arm-linux-gnueabi- SPL is too big by 0x36 bytes
arm-linux-gnueabihf- SPL fits by 0x2a bytes
arm-none-eabi- SPL fits by 0xa bytes

(Those figures are from builds with the expanded SPL size allocation,
relative to the non-expanded SPL size limit; they're better by about
6 bytes in the more constrained build.)

ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalization

As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.

The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.

I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.

The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such,
some CPU errata exist, and must be worked around.

These must be worked around in the bootloader, since in general, the
kernel (especially a multi-platform kernel) needs to support being
launched in non-secure mode (normal world), and hence may not be able
to write to the CP15 register to enable these workarounds.

mmc: tegra: use bounce buffer APIs

Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In
some cases (e.g. user load commands) this cannot be guaranteed by callers
of the MMC APIs. To solve this, modify the Tegra MMC driver to use the
new bounce_buffer_*() APIs.

Note: Ideally, all U-Boot code will always provide address- and size-
aligned buffers, so a bounce buffer will only ever be needed for user-
supplied buffers (e.g. load commands). Ensuring this removes the need
for performance-sucking bounce buffer cache management and memcpy()s.
The one known exception at present is the SCR buffer in sd_change_freq(),
which is only 8 bytes long. Solving this requires enhancing struct
mmc_data to know the difference between buffer size and transferred data
size, or forcing all callers of mmc_send_cmd() to have allocated buffers
using ALLOC_CACHE_ALIGN_BUFFER(), which while true in this case, is not
enforced in any way at present, and so cannot be assumed by the core MMC
code.

ARM: tegra: define CONFIG_SYS_BOOTMAPSZ

This define indicates the size of the memory region where it is safe
to place data passed to the Linux kernel (ATAGs, DTB, initrd). The
value needs to be:

a) Less than or equal to RAM size.
b) Small enough that the area is not within the kernel's highmem region,
since the kernel cannot access ATAGs/DTB/initrd from highmem.
c) Large enough to hold the kernel+DTB+initrd.

256M seems large enough for (c) in most circumstances, and small enough
to satisfy (a) and (b) across any possible Tegra board. Note that the
user can override this value via environment variable "bootm_mapsize"
if needed.

The advantage of defining BOOTMAPSZ is that we no longer need to define
variable fdt_high in the default environment. Previously, we defined
this to prevent the DTB from being relocated to the very end of RAM,
which on most Tegra systems is within highmem, and hence which would
cause boot failures. A user can still define this variable themselves
if they want the FDT to be either left in-place wherever loaded, or
copied to some other specific location. Similarly, there should no
longer be a strict requirement for the user to define initrd_high if
using an initrd.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all

so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

ARM: tegra: expand all SPL sizes to be consistent

The size allocation for SPL is increased in all cases to match the
already-expanded value used on Tegra124. This is both for general
consistency, and because the seaboard build trips over the limit already
when using one of the ARM compilers packaged with 14.04. For the record,
when building Seaboard:

arm-linux-gnueabi- SPL is too big by 0x36 bytes
arm-linux-gnueabihf- SPL fits by 0x2a bytes
arm-none-eabi- SPL fits by 0xa bytes

(Those figures are from builds with the expanded SPL size allocation,
relative to the non-expanded SPL size limit; they're better by about
6 bytes in the more constrained build.)

ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalization

As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.

The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.

I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.

The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

ARM: tegra: enable some CPU errata workarounds

Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such,
some CPU errata exist, and must be worked around.

These must be worked around in the bootloader, since in general, the

mmc: tegra: use bounce buffer APIs

Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In
some cases (e.g. user load commands) this cannot be guaranteed by callers
of the MMC APIs. To solve this, modify the Tegra MMC driver to use the
new bounce_buffer_*() APIs.

Note: Ideally, all U-Boot code will always provide address- and size-
aligned buffers, so a bounce buffer will only ever be needed for user-
supplied buffers (e.g. load commands). Ensuring this removes the need
for performance-sucking bounce buffer cache management and memcpy()s.
The one known exception at present is the SCR buffer in sd_change_freq(),
which is only 8 bytes long. Solving this requires enhancing struct
mmc_data to know the difference between buffer size and transferred data
size, or forcing all callers of mmc_send_cmd() to have allocated buffers
using ALLOC_CACHE_ALIGN_BUFFER(), which while true in this case, is not
enforced in any way at present, and so cannot be assumed by the core MMC
code.

ARM: tegra: define CONFIG_SYS_BOOTMAPSZ

This define indicates the size of the memory region where it is safe
to place data passed to the Linux kernel (ATAGs, DTB, initrd). The
value needs to be:

a) Less than or equal to RAM size.
b) Small enough that the area is not within the kernel's highmem region,
since the kernel cannot access ATAGs/DTB/initrd from highmem.
c) Large enough to hold the kernel+DTB+initrd.

256M seems large enough for (c) in most circumstances, and small enough
to satisfy (a) and (b) across any possible Tegra board. Note that the
user can override this value via environment variable "bootm_mapsize"
if needed.

The advantage of defining BOOTMAPSZ is that we no longer need to define
variable fdt_high in the default environment. Previously, we defined
this to prevent the DTB from being relocated to the very end of RAM,
which on most Tegra systems is within highmem, and hence which would
cause boot failures. A user can still define this variable themselves
if they want the FDT to be either left in-place wherever loaded, or
copied to some other specific location. Similarly, there should no
longer be a strict requirement for the user to define initrd_high if
using an initrd.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

ARM: Move SYS_CACHELINE_SIZE over to Kconfig

This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all

so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

ARM: tegra: expand all SPL sizes to be consistent

The size allocation for SPL is increased in all cases to match the
already-expanded value used on Tegra124. This is both for general
consistency, and because the seaboard build trips over the limit already
when using one of the ARM compilers packaged with 14.04. For the record,
when building Seaboard:

arm-linux-gnueabi- SPL is too big by 0x36 bytes
arm-linux-gnueabihf- SPL fits by 0x2a bytes
arm-none-eabi- SPL fits by 0xa bytes

(Those figures are from builds with the expanded SPL size allocation,
relative to the non-expanded SPL size limit; they're better by about
6 bytes in the more constrained build.)

ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalization

As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.

The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.

I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.

The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

ARM: tegra: enable a common set of disk-related commands everywhere

Enable a common set of partition types, filesystems, and related
commands in tegra-common.h, so that they are available on all Tegra
boards. This allows boot.scr (loaded and executed by the default
built-in environment) on those boards to assume that certain features
are always available.

Do this in tegra-common.h, so that individual board files can undefine
the features if they really don't want any of them.

ARM: tegra: enable some CPU errata workarounds

Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such,
some CPU errata exist, and must be worked around.

These must be worked around in the bootloader, since in general, the
kernel (especially a multi-platform kernel) needs to support being
launched in non-secure mode (normal world), and hence may not be able
to write to the CP15 register to enable these workarounds.
