it is necessary to tighten the check on the 'size' variable on line 463.

tools/imximage: get HAB information from header

Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.

The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the
information in the flash header of the imximage.
The advantage of using information from flash header is, that they are
not only available during image creation, but also available if
existing images are processed.

$ tools/mkimage -l u-boot.imx

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.

tools/imximage: Fix fruity lack of 0x prefix in DCD Blocks

commit 8519c9c98ad6 ("tools/imximage: use 0x prefix in HAB Blocks line")
adds an 0x prefix to each HAB Block number to make it easier for host tools
to process the HAB Block output, however it neglects to apply the same
prefix to the DCD Blocks directive. You need the DCD Blocks directive if
you are making a u-boot recovery image which the BootROM will accept via
the USB upload utility.

This disparity results in a fruity output like this with HAB Blocks
prefixed but DCD Blocks not prefixed - which is pretty inconsistent.

This patch fixes the difference assuming the original commit was a

imximage: Remove failure when no IVT offset is found

Sometimes imximage throws the following error:

CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
MKIMAGE u-boot-dtb.imx
Error: No BOOT_FROM tag in board/freescale/vf610twr/imximage.cfg.cfgtmp
arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed

Later on, when running mkimage for the u-boot.imx it will succeed in
finding the IVT offset.

Looks like some race condition happening during parallel build when
processing mkimage for u-boot-dtb.imx and u-boot.imx.

A proper fix still needs to be implemented, but as a workaround let's
remove the error when the IVT offset is not found.

It is useful to have such message, especially during bring-up phase,
but the build error that it causes is severe, so better avoid the
build error for now.

The error checking can be re-implemented later when we have a proper
fix.

memory where the image is loaded to, there are hundreds of bytes at

This modification also weakens the coupling between image types (FIT, IMX, MXS,
and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
"imagetool" through register_image_tool() function, while the image types
register themselves within an image tool using the register_image_type()
function:

+---------------+

Also, the struct "mkimage_params" was renamed to "image_tool_params" to make

imximage: Remove overwriting of flash_offset

The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).

The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().

Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.

If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.

tools/imximage: get HAB information from header

Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.

The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the
information in the flash header of the imximage.
The advantage of using information from flash header is, that they are
not only available during image creation, but also available if
existing images are processed.

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.

tools/imximage: Fix fruity lack of 0x prefix in DCD Blocks

commit 8519c9c98ad6 ("tools/imximage: use 0x prefix in HAB Blocks line")
adds an 0x prefix to each HAB Block number to make it easier for host tools
to process the HAB Block output, however it neglects to apply the same
prefix to the DCD Blocks directive. You need the DCD Blocks directive if
you are making a u-boot recovery image which the BootROM will accept via
the USB upload utility.

This disparity results in a fruity output like this with HAB Blocks
prefixed but DCD Blocks not prefixed - which is pretty inconsistent.

imximage: Remove failure when no IVT offset is found

Sometimes imximage throws the following error:

CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
MKIMAGE u-boot-dtb.imx

Later on, when running mkimage for the u-boot.imx it will succeed in
finding the IVT offset.

Looks like some race condition happening during parallel build when
processing mkimage for u-boot-dtb.imx and u-boot.imx.

A proper fix still needs to be implemented, but as a workaround let's
remove the error when the IVT offset is not found.

It is useful to have such message, especially during bring-up phase,
but the build error that it causes is severe, so better avoid the
build error for now.

The error checking can be re-implemented later when we have a proper
fix.

register themselves within an image tool using the register_image_type()

Implement BOOT_OFFSET command for imximage. This command is parallel
to current BOOT_FROM command, but allows more flexibility in configuring
arbitrary image header offset. Also add an imximage.cfg with default
offset values into arm/arch/imx-common/ so the board-specific imximage.cfg
can include this file to avoid magic constants.

The syntax of BOOT_OFFSET command is "BOOT_OFFSET <u32 offset>".

Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:

"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot

imximage: Remove overwriting of flash_offset

The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).

The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().

Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.

If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.

tools/imximage: get HAB information from header

Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.

The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the
information in the flash header of the imximage.
The advantage of using information from flash header is, that they are
not only available during image creation, but also available if
existing images are processed.

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.

tools/imximage: Fix fruity lack of 0x prefix in DCD Blocks

commit 8519c9c98ad6 ("tools/imximage: use 0x prefix in HAB Blocks line")
adds an 0x prefix to each HAB Block number to make it easier for host tools
to process the HAB Block output, however it neglects to apply the same
prefix to the DCD Blocks directive. You need the DCD Blocks directive if
you are making a u-boot recovery image which the BootROM will accept via

imximage: Remove failure when no IVT offset is found

Sometimes imximage throws the following error:

CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
MKIMAGE u-boot-dtb.imx

arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed

Later on, when running mkimage for the u-boot.imx it will succeed in
finding the IVT offset.

Looks like some race condition happening during parallel build when
processing mkimage for u-boot-dtb.imx and u-boot.imx.

A proper fix still needs to be implemented, but as a workaround let's
remove the error when the IVT offset is not found.

It is useful to have such message, especially during bring-up phase,
but the build error that it causes is severe, so better avoid the
build error for now.

The error checking can be re-implemented later when we have a proper
fix.

This modification also weakens the coupling between image types (FIT, IMX, MXS,

"imagetool" through register_image_tool() function, while the image types
register themselves within an image tool using the register_image_type()
function:

allocate the IVT, Boot Data and DCD at correct locations
depending on the boot media.

Also check that the Image Vector Table Offset + IVT +
Boot Data + DCD <= Initial Load Region Size.

Previously struct imx_header was always 4096 bytes and was
not dealing correctly with the Image Vector Table Offset.

Now, the memory allocation looks for e.g. SD boot like this

Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:

"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot
be packaged."

imximage: Remove overwriting of flash_offset

The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).

The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().

Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.

If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.

tools/imximage: get HAB information from header

Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.

The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the
information in the flash header of the imximage.
The advantage of using information from flash header is, that they are
not only available during image creation, but also available if
existing images are processed.

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.

tools/imximage: Fix fruity lack of 0x prefix in DCD Blocks

commit 8519c9c98ad6 ("tools/imximage: use 0x prefix in HAB Blocks line")
adds an 0x prefix to each HAB Block number to make it easier for host tools
to process the HAB Block output, however it neglects to apply the same
prefix to the DCD Blocks directive. You need the DCD Blocks directive if
you are making a u-boot recovery image which the BootROM will accept via
the USB upload utility.

This disparity results in a fruity output like this with HAB Blocks
prefixed but DCD Blocks not prefixed - which is pretty inconsistent.

imximage: Remove failure when no IVT offset is found

Sometimes imximage throws the following error:

CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
MKIMAGE u-boot-dtb.imx

arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed

Later on, when running mkimage for the u-boot.imx it will succeed in
finding the IVT offset.

Looks like some race condition happening during parallel build when
processing mkimage for u-boot-dtb.imx and u-boot.imx.

A proper fix still needs to be implemented, but as a workaround let's
remove the error when the IVT offset is not found.

It is useful to have such message, especially during bring-up phase,
but the build error that it causes is severe, so better avoid the
build error for now.

The error checking can be re-implemented later when we have a proper
fix.

memory. It means the bootdata.size should contain the IVT offset part,
but the calculation in imximage tool does not have.

We found this issue when booting from QuadSPI NOR on i.MX6SX. The u-boot
runs into abnormal (crash or stop) after booting. After checked the destination
memory where the image is loaded to, there are hundreds of bytes at
the image end are not loaded into memory. Since there is a 4096 bytes
round in the calculation, for the booting devices using smaller IVT offset,
such as SD and SPI booting, they are not easy to reproduce.

imximage: Fix imximage IVT bug for EIM-NOR boot

The load region size of EIM-NOR are defined to 0. For this case,
the parameter "imximage_init_loadsize" must be calculated.
The imximage tool implements the calculation in the "imximage_generate"
function, but the following function "imximage_set_header" resets the value
and not calculate. This bug cause some fields of IVT head are not
correct, for example the boot_data and DCD overlay the application area.

tools: moved code common to all image tools to a separated module.

In order to avoid duplicating code and keep only one point of modification,
the functions, structs and defines useful for "dumpimage" were moved from
"mkimage" to a common module called "imagetool".

This modification also weakens the coupling between image types (FIT, IMX, MXS,
and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
"imagetool" through register_image_tool() function, while the image types
register themselves within an image tool using the register_image_type()
function:

+---------------+
+------| fit_image |
+--------------+ +-----------+ | +---------------+
| mkimage |--------> | | <-----+
+--------------+ | | +---------------+
| imagetool | <------------| imximage |
+--------------+ | | +---------------+
| dumpimage |--------> | | <-----+
+--------------+ +-----------+ | +---------------+
+------| default_image |
+---------------+

register_image_tool() register_image_type()

Also, the struct "mkimage_params" was renamed to "image_tool_params" to make
clear its general purpose.

Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:

"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these

imximage: Remove overwriting of flash_offset

The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).

The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().

Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.

If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.

tools/imximage: get HAB information from header

Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.

The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the
information in the flash header of the imximage.
The advantage of using information from flash header is, that they are
not only available during image creation, but also available if
existing images are processed.

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.

imximage: Remove failure when no IVT offset is found

Sometimes imximage throws the following error:

CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
MKIMAGE u-boot-dtb.imx

arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed

Later on, when running mkimage for the u-boot.imx it will succeed in
finding the IVT offset.

Looks like some race condition happening during parallel build when
processing mkimage for u-boot-dtb.imx and u-boot.imx.

A proper fix still needs to be implemented, but as a workaround let's
remove the error when the IVT offset is not found.

It is useful to have such message, especially during bring-up phase,
but the build error that it causes is severe, so better avoid the
build error for now.

The error checking can be re-implemented later when we have a proper
fix.

imximage: Fix the bootdata.size calculation

In system boot chapter of i.MX6 reference manual, the "Image Vector Table"
figure shows the bootdata.start points to the beginning of the destination
memory. It means the bootdata.size should contain the IVT offset part,
but the calculation in imximage tool does not have.

We found this issue when booting from QuadSPI NOR on i.MX6SX. The u-boot
runs into abnormal (crash or stop) after booting. After checked the destination
memory where the image is loaded to, there are hundreds of bytes at
the image end are not loaded into memory. Since there is a 4096 bytes
round in the calculation, for the booting devices using smaller IVT offset,
such as SD and SPI booting, they are not easy to reproduce.

tools: moved code common to all image tools to a separated module.

In order to avoid duplicating code and keep only one point of modification,
the functions, structs and defines useful for "dumpimage" were moved from
"mkimage" to a common module called "imagetool".

This modification also weakens the coupling between image types (FIT, IMX, MXS,
and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
"imagetool" through register_image_tool() function, while the image types
register themselves within an image tool using the register_image_type()
function:

+---------------+
+------| fit_image |
+--------------+ +-----------+ | +---------------+
| mkimage |--------> | | <-----+
+--------------+ | | +---------------+

+--------------+ +-----------+ | +---------------+
+------| default_image |
+---------------+

Also, the struct "mkimage_params" was renamed to "image_tool_params" to make
clear its general purpose.

Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:

"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot

imximage: Remove overwriting of flash_offset

The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).

The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().

Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.

If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.

tools/imximage: get HAB information from header

Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.

The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the
information in the flash header of the imximage.
The advantage of using information from flash header is, that they are
not only available during image creation, but also available if
existing images are processed.

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.

commit 8519c9c98ad6 ("tools/imximage: use 0x prefix in HAB Blocks line")
adds an 0x prefix to each HAB Block number to make it easier for host tools

you are making a u-boot recovery image which the BootROM will accept via
