Generate include/generated/generic-asm-offsets.h and
include/generated/asm-offsets.h in ./Kbuild.This commit also changes the include guard.
Before this commit, __ASM_OFFSETS_H__ was used for both of them.
So we could not include generic-asm-offsets.h and asm-offsets.h
at the same time.This commit renames the include guard of the former to
__GENERIC_ASM_OFFSETS_H__.Signed-off-by: Masahiro Yamada

fw_printenv is a program which mostly runs on the target Linux.
Before switching to Kbuild, we needed to set HOSTCC at the
command line like this:
make HOSTCC= envGoing forward we can cross compile it by specifying CROSS_COMPILE:
make CROSS_COMPILE= env
This looks more natural.Signed-off-by: Masahiro Yamada

Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build objWe need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.Additionally, we need to fix compiler flags which are
locally added or removed.In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.Signed-off-by: Masahiro Yamada

This commit changes the working directory
where the build process occurs.Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-bootHere, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.And our old build system changes the current working directory
with "make -C " syntax when descending into the
sub-directories.On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj="
syntax for descending into sub-directories.
(We can write it like "make $(obj)=" with a shorthand.)
This means the current working directory is always the top
of the output directory.Signed-off-by: Masahiro Yamada

ARM64 uses the newer RELA-style relocations rather than the older REL.
RELA relocations have an addend in the relocation struct, rather than
expecting the loader to read a value from the location to be updated.While this is beneficial for ordinary program loading, it's problematic
for U-Boot because the location to be updated starts out with zero,
rather than a pre-relocation value. Since we need to be able to run C
code before relocation, we need a tool to apply the relocations at
build time.In theory this tool is applicable to other newer architectures (mainly
64-bit), but currently the only relocations it supports are for arm64,
and it assumes a 64-bit little-endian target. If the latter limitation
is ever to be changed, we'll need a way to tell the tool what format
the image is in. Eventually this may be replaced by a tool that uses
libelf or similar and operates directly on the ELF file. I've written
some code for such an approach but libelf does not make it easy to poke
addresses by memory address (rather than by section), and I was
hesitant to write code to manually parse the program headers and do the
update outside of libelf (or to iterate over sections) -- especially
since it wouldn't get test coverage on things like binaries with
multiple PT_LOAD segments. This should be good enough for now to let
the manual relocation stuff be removed from the arm64 patches.Signed-off-by: Scott Wood

When variable size SPL is used, the BL1 expects the SPL to be
encapsulated differently: instead of putting the checksum at a fixed
offset in the SPL blob, prepend the blob with a header including the
size and the checksum.The enhancements include
- adding a command line option, '--vs' to indicate the need for the
variable size encapsulation
- padding the fixed size encapsulated blob with 0xff instead of random
memory contents
- do not silently truncate the input file, report error instead
- no need to explicitly closing files/freeing memory, this all happens
on exit; removing cleanups it makes code clearer
- profuse commenting
- modify Makefile to allow enabling the new feature per boardSigned-off-by: Vadim Bendebury

According to NOTE in strtoul(3), the errno must be zeroed before strtoul()
is called. Zero the errno. The NOTE reads as such:Since strtoul() can legitimately return 0 or ULONG_MAX (ULLONG_MAX for
strtoull()) on both success and failure, the calling program should set
errno to 0 before the call, and then determine if an error occurred
by checking whether errno has a nonzero value after the call.This issue was detected on Fedora 19 with glibc 2.17 .

We have some scripts imported from Linux Kernel:
setlocalversion, checkstack.pl, checkpatch.pl, cleanpatchThey are located under tools/ directory in U-Boot now.
But they were originally located under scripts/ directory
in Linux Kernel.This commit moves them to the original location.
It is true that binutils-version.sh and dtc-version.sh
do not originate in Linux Kernel, but they should
be moved by analogy to gcc-version.sh.Signed-off-by: Masahiro Yamada

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.imgImage 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 MBIt 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.Signed-off-by: Guilherme Maciel Ferreira
Signed-off-by: Simon Glass -
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:+---------------+

A common use-case is to build all boards for a particular SoC. This can
be achieved by:./tools/buildman/buildman -b mainline_dev tegra20
However, when the SoC is a member of a family of SoCs, and each SoC has
a different name, it would be even more useful to build all boards for
every SoC in that family. This currently isn't possible since buildman's
board selection command-line arguments are compared to board definitions
using pure string equality.To enable this, compare using a regex match instead. This matches
MAKEALL's handling of command-line arguments. This enables:(all Tegra)

When a toolchain invocation fails, an exception is thrown but not caught
which then aborts the entire toolchain detection process. To solve this,
request that exceptions not be thrown, since the toolchain init code
already error-checks the command result. This solves e.g.:- found '/usr/bin/winegcc'
Traceback (most recent call last):
