tools: gitignore: Fix tools/generated path

'git status' shows 'tools/generated/' after running the build, which is
wrong. The corresponding .gitignore rule was already added in commit
c623642d29be ("Adjust gitignore for tools/generated/"), but because of
superfluous 'tools/' part it wasn't in effect. Remove incorrect 'tools/'
part to fix it.

While at it, remove tools/ path incorrectly added to the top-level
.gitignore in commit 801c482207c7 (".gitignore: ignore misc include,
simple-bin, and tools/generated build artifacts"), as it's required in
the comment on the top of .gitignore:

# NOTE! Don't add files that are generated in specific
# subdirectories here. Add them in the ".gitignore" file
# in that subdirectory instead.

tools: add fdt_add_pubkey

Having to use the -K option to mkimage to populate U-Boot's .dtb with the
public key while signing the kernel FIT image is often a little
awkward. In particular, when using a meta-build system such as
bitbake/Yocto, having the tasks of the kernel and U-Boot recipes
intertwined, modifying deployed artifacts and rebuilding U-Boot with
an updated .dtb is quite cumbersome. Also, in some scenarios one may
wish to build U-Boot complete with the public key(s) embedded in the
.dtb without the corresponding private keys being present on the same
build host.

So this adds a simple tool that allows one to disentangle the kernel
and U-Boot builds, by simply copy-pasting just enough of the mkimage
code to allow one to add a public key to a .dtb. When using mkimage,
some of the information is taken from the .its used to build the
kernel (algorithm and key name), so that of course needs to be
supplied on the command line.

tools: Avoid creating symbolic links for tools/version.h

When building U-Boot host tools for Windows from Microsoft Azure
Pipelines, the following errors were seen:

HOSTCC tools/mkenvimage.o

It turns out tools/version.h is a symbolic link and with Windows
default settings it is unsupported hence the actual content of
tools/version.h is not what file include/version.h has, but the
the linked file path, which breaks the build.

To fix this, remove the symbolic links for tools/version.h. Instead
we perform a copy from include/version.h during the build.

tools: provide a tool to convert a binary file to an include

For testing EFI disk management we need an in-memory image of
a disk.

The tool file2include converts a file to a C include. The file
is separated into strings of 8 bytes. Only the non-zero strings
are written to the include. The output format has been designed
to maintain readability.

#define EFI_ST_DISK_IMG { 0x00010000, { \
{0x000001b8, "\x94\x37\x69\xfc\x00\x00\x00\x00"}, /* .7i..... */ \

As the disk image needed for testing contains mostly zeroes a high
compression ratio can be attained.

pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

MIPS: Stop building position independent code

U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.

Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:

8f998064 lw t9,-32668(gp)
0320f809 jalr t9

Without -fpic the call is simply:

0f803f01 jal be00fc04 <puts>

This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.

Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:

3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9

Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.

This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.

Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

multi.img

Image Name: x86
Created: Thu Jul 25 10:29:13 2013
Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
Load Address: 00000000
Entry Point: 00000000
Contents:
Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB

It is possible to perform the innverse operation -- extracting any file from
the image -- by using the dumpimage's -i option:

$ dumpimage -i multi.img -p 2 System.map

Although it's feasible to retrieve "data files" from image through scripting,
the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
is cumbersome and unreliable -- once you must keep track of file sizes inside
the image. Furthermore, extracting data files using "dumpimage" tool is faster
than through scripting.

kerneldoc: Implant DocBook from Linux kernel

Pull slightly modified version of Documentation/DocBook, the related perl
script scripts/kernel-doc and the scripts/docproc.c from Linux kernel and
implant it into U-Boot. This will allow smooth generation of kerneldoc
style documentation.

It was necessary to modify the DocBook/Makefile to work with U-Boot build
system. The changes were only minor though and involved replacing the kbuild
specific parts.

It was also necessary to replace use of variables like KERNEL_VERSION with
U_BOOT_VERSION, strings like Linux kernel with U-Boot Bootloader etc. so
the generated result actually matches.

Finally, it was necessary to adjust docproc.c, since the documentation in
U-Boot is located in doc/DocBook instead of Documentation/DocBook as is in
case of the Linux kernel.

Some parts of the DocBook Makefile are unused, but to allow easier sync with
Linux kernel, these parts are still left in. The targets enabled now are
"htmldocs" "pdfdocs" "psdocs" "xmldocs" and "cleandocs" to remove the results
of documentation build.

tools: Avoid creating symbolic links for tools/version.h

Pipelines, the following errors were seen:

HOSTCC tools/mkenvimage.o

It turns out tools/version.h is a symbolic link and with Windows
default settings it is unsupported hence the actual content of
tools/version.h is not what file include/version.h has, but the
the linked file path, which breaks the build.

To fix this, remove the symbolic links for tools/version.h. Instead
we perform a copy from include/version.h during the build.

tools: provide a tool to convert a binary file to an include

For testing EFI disk management we need an in-memory image of
a disk.

The tool file2include converts a file to a C include. The file
is separated into strings of 8 bytes. Only the non-zero strings
are written to the include. The output format has been designed
to maintain readability.

#define EFI_ST_DISK_IMG { 0x00010000, { \

As the disk image needed for testing contains mostly zeroes a high
compression ratio can be attained.

pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

MIPS: Stop building position independent code

U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.

Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:

8f998064 lw t9,-32668(gp)
0320f809 jalr t9

Without -fpic the call is simply:

0f803f01 jal be00fc04 <puts>

This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.

Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:

3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9

Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.

This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.

Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

Given a multi-file image created through the mkimage's -d option:

$ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \
multi.img

Image Name: x86
Created: Thu Jul 25 10:29:13 2013
Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
Load Address: 00000000
Entry Point: 00000000
Contents:
Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB

It is possible to perform the innverse operation -- extracting any file from
the image -- by using the dumpimage's -i option:

$ dumpimage -i multi.img -p 2 System.map

Although it's feasible to retrieve "data files" from image through scripting,
the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
is cumbersome and unreliable -- once you must keep track of file sizes inside
the image. Furthermore, extracting data files using "dumpimage" tool is faster
than through scripting.

kerneldoc: Implant DocBook from Linux kernel

Pull slightly modified version of Documentation/DocBook, the related perl
script scripts/kernel-doc and the scripts/docproc.c from Linux kernel and
implant it into U-Boot. This will allow smooth generation of kerneldoc
style documentation.

It was necessary to modify the DocBook/Makefile to work with U-Boot build
system. The changes were only minor though and involved replacing the kbuild
specific parts.

It was also necessary to replace use of variables like KERNEL_VERSION with
U_BOOT_VERSION, strings like Linux kernel with U-Boot Bootloader etc. so
the generated result actually matches.

Finally, it was necessary to adjust docproc.c, since the documentation in
U-Boot is located in doc/DocBook instead of Documentation/DocBook as is in
case of the Linux kernel.

Some parts of the DocBook Makefile are unused, but to allow easier sync with
Linux kernel, these parts are still left in. The targets enabled now are
"htmldocs" "pdfdocs" "psdocs" "xmldocs" and "cleandocs" to remove the results
of documentation build.

tools: add fdt_add_pubkey

Having to use the -K option to mkimage to populate U-Boot's .dtb with the
public key while signing the kernel FIT image is often a little
awkward. In particular, when using a meta-build system such as
bitbake/Yocto, having the tasks of the kernel and U-Boot recipes
intertwined, modifying deployed artifacts and rebuilding U-Boot with
an updated .dtb is quite cumbersome. Also, in some scenarios one may
wish to build U-Boot complete with the public key(s) embedded in the
.dtb without the corresponding private keys being present on the same
build host.

So this adds a simple tool that allows one to disentangle the kernel
and U-Boot builds, by simply copy-pasting just enough of the mkimage
code to allow one to add a public key to a .dtb. When using mkimage,
some of the information is taken from the .its used to build the
kernel (algorithm and key name), so that of course needs to be
supplied on the command line.

pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

The pylibfdt is used by dtoc (and, indirectly by binman), but there

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

MIPS: Stop building position independent code

U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.

Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:

8f998064 lw t9,-32668(gp)
0320f809 jalr t9

Without -fpic the call is simply:

0f803f01 jal be00fc04 <puts>

This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.

Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:

3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9

Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.

This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.

Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

Given a multi-file image created through the mkimage's -d option:

$ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \
multi.img

Image Name: x86
Created: Thu Jul 25 10:29:13 2013
Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
Load Address: 00000000
Entry Point: 00000000
Contents:
Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB

It is possible to perform the innverse operation -- extracting any file from
the image -- by using the dumpimage's -i option:

$ dumpimage -i multi.img -p 2 System.map

Although it's feasible to retrieve "data files" from image through scripting,
the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
is cumbersome and unreliable -- once you must keep track of file sizes inside
the image. Furthermore, extracting data files using "dumpimage" tool is faster
than through scripting.

kerneldoc: Implant DocBook from Linux kernel

Pull slightly modified version of Documentation/DocBook, the related perl
script scripts/kernel-doc and the scripts/docproc.c from Linux kernel and
implant it into U-Boot. This will allow smooth generation of kerneldoc
style documentation.

It was necessary to modify the DocBook/Makefile to work with U-Boot build
system. The changes were only minor though and involved replacing the kbuild
specific parts.

It was also necessary to replace use of variables like KERNEL_VERSION with
U_BOOT_VERSION, strings like Linux kernel with U-Boot Bootloader etc. so
the generated result actually matches.

Finally, it was necessary to adjust docproc.c, since the documentation in
U-Boot is located in doc/DocBook instead of Documentation/DocBook as is in
case of the Linux kernel.

Some parts of the DocBook Makefile are unused, but to allow easier sync with
Linux kernel, these parts are still left in. The targets enabled now are
"htmldocs" "pdfdocs" "psdocs" "xmldocs" and "cleandocs" to remove the results
of documentation build.

kerneldoc: Implant DocBook from Linux kernel

Pull slightly modified version of Documentation/DocBook, the related perl
script scripts/kernel-doc and the scripts/docproc.c from Linux kernel and
implant it into U-Boot. This will allow smooth generation of kerneldoc
style documentation.

It was necessary to modify the DocBook/Makefile to work with U-Boot build
system. The changes were only minor though and involved replacing the kbuild
specific parts.

It was also necessary to replace use of variables like KERNEL_VERSION with
U_BOOT_VERSION, strings like Linux kernel with U-Boot Bootloader etc. so
the generated result actually matches.

Finally, it was necessary to adjust docproc.c, since the documentation in
U-Boot is located in doc/DocBook instead of Documentation/DocBook as is in
case of the Linux kernel.

Some parts of the DocBook Makefile are unused, but to allow easier sync with
Linux kernel, these parts are still left in. The targets enabled now are
"htmldocs" "pdfdocs" "psdocs" "xmldocs" and "cleandocs" to remove the results
of documentation build.

Pipelines, the following errors were seen:

HOSTCC tools/mkenvimage.o

It turns out tools/version.h is a symbolic link and with Windows
default settings it is unsupported hence the actual content of
tools/version.h is not what file include/version.h has, but the
the linked file path, which breaks the build.

To fix this, remove the symbolic links for tools/version.h. Instead
we perform a copy from include/version.h during the build.

tools: provide a tool to convert a binary file to an include

For testing EFI disk management we need an in-memory image of

The tool file2include converts a file to a C include. The file
is separated into strings of 8 bytes. Only the non-zero strings
are written to the include. The output format has been designed
to maintain readability.

#define EFI_ST_DISK_IMG { 0x00010000, { \

As the disk image needed for testing contains mostly zeroes a high

pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

MIPS: Stop building position independent code

U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.

Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:

8f998064 lw t9,-32668(gp)
0320f809 jalr t9

Without -fpic the call is simply:

0f803f01 jal be00fc04 <puts>

This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.

Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:

3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9

Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.

This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.

Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

Pull slightly modified version of Documentation/DocBook, the related perl
script scripts/kernel-doc and the scripts/docproc.c from Linux kernel and

It was necessary to modify the DocBook/Makefile to work with U-Boot build

It was also necessary to replace use of variables like KERNEL_VERSION with
U_BOOT_VERSION, strings like Linux kernel with U-Boot Bootloader etc. so
the generated result actually matches.

Finally, it was necessary to adjust docproc.c, since the documentation in

case of the Linux kernel.

Some parts of the DocBook Makefile are unused, but to allow easier sync with
Linux kernel, these parts are still left in. The targets enabled now are
"htmldocs" "pdfdocs" "psdocs" "xmldocs" and "cleandocs" to remove the results

tools: Avoid creating symbolic links for tools/version.h

When building U-Boot host tools for Windows from Microsoft Azure
Pipelines, the following errors were seen:

HOSTCC tools/mkenvimage.o

make[2]: *** [scripts/Makefile.host:114: tools/mkenvimage.o] Error 1

It turns out tools/version.h is a symbolic link and with Windows
default settings it is unsupported hence the actual content of
tools/version.h is not what file include/version.h has, but the
the linked file path, which breaks the build.

To fix this, remove the symbolic links for tools/version.h. Instead
we perform a copy from include/version.h during the build.

tools: provide a tool to convert a binary file to an include

For testing EFI disk management we need an in-memory image of
a disk.

The tool file2include converts a file to a C include. The file
is separated into strings of 8 bytes. Only the non-zero strings
are written to the include. The output format has been designed
to maintain readability.

#define EFI_ST_DISK_IMG { 0x00010000, { \
{0x000001b8, "\x94\x37\x69\xfc\x00\x00\x00\x00"}, /* .7i..... */ \

As the disk image needed for testing contains mostly zeroes a high
compression ratio can be attained.

pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

MIPS: Stop building position independent code

U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.

Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:

8f998064 lw t9,-32668(gp)
0320f809 jalr t9

Without -fpic the call is simply:

0f803f01 jal be00fc04 <puts>

This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.

Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:

3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9

Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.

This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.

Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

Given a multi-file image created through the mkimage's -d option:

$ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \
multi.img

Image Name: x86
Created: Thu Jul 25 10:29:13 2013
Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
Load Address: 00000000
Entry Point: 00000000
Contents:
Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB

It is possible to perform the innverse operation -- extracting any file from
the image -- by using the dumpimage's -i option:

$ dumpimage -i multi.img -p 2 System.map

Although it's feasible to retrieve "data files" from image through scripting,
the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
is cumbersome and unreliable -- once you must keep track of file sizes inside
the image. Furthermore, extracting data files using "dumpimage" tool is faster
than through scripting.
