7a439cadcf mkimage: fix argument parsing on BSD systems
The getopt(3) optstring '-' is a GNU extension which is not available on BSD
systems like OS X.

Remove this dependency by implementing argument parsing in another way. This
will also change the lately introduced '-b' switch behaviour.

8a7367acca cmd: Fix license command
The license command isn't usually built and has a few problems:
- The rules to generate license.h haven't worked in a long time,
  re-write these based on the bmp_logo.h rules.
- 'tok' is unused and the license text size has increased
- bin2header.c wasn't grabbing unistd.h to know the prototype for
  read().

0adf8d3548 x86: Add support for running Intel reference code
Intel has invented yet another binary blob which firmware is required to
run. This is run after SDRAM is ready. It is linked to load at a particular
address, typically 0, but is a relocatable ELF so can be moved if required.

Add support for this in the build system. The file should be placed in the
board directory, and called refcode.elf.

15b51878be Makefile: remove BUILD_TAG from KBUILD_CFLAGS
If BUILD_TAG is part of KBUILD_CFLAGS, then any time the value changes,
all files get rebuilt. In a continuous integration environment, the value
will change every build. This wastes time, assuming that incremental
builds would otherwise occur.

To solve this, remove BUILD_TAG from KBUILD_CFLAGS and add it to CFLAGS
for just the one file that uses it. This does have the disadvantage that
if any other files want to use the flag, we'll need to duplicate this
custom CFLAGS setup logic. However, it seems unlikely we'll need this.

An alternative would be to add BUILD_TAG to the "local version" and remove
the special case code from display_options.c. However, that would affect
the format of the U-Boot signon message, which may negatively affect
people looking for specific data there. The approach of using
file-specific CFLAGS was suggested by Masahiro Yamada.

ad1ecd2063 fdt: Build a U-Boot binary without device tree
At present u-boot.bin holds the plain U-Boot binary without the device tree.
This is somewhat annoying since you need either u-boot.bin or u-boot-dtb.bin
depending on whether device tree is used.

Adjust the build such that u-boot.bin includes a device tree (if enabled),
and the plain binary is in u-boot-nodtb.bin. For now u-boot-dtb.bin remains
the same.

This should be acceptable since:

- without OF_CONTROL, u-boot.bin still does not include a device tree
- with OF_CONTROL, u-boot-dtb.bin does not change

The main impact is build systems which are set up to use u-boot.bin as
the output file and then add a device tree. These will have to change to use
u-boot-nodtb.bin instead.

Adjust tegra rules so it continues to produce the correct files.

72a8cf8dcc Move all command code into its own directory
There are a lot of unrelated files in common, including all of the commands.
Moving them into their own directory makes them easier to find and is more
logical.

Some commands include non-command code, such as cmd_scsi.c. This should be
sorted out at some point so that the function can be enabled with or without
the associated command.

Unfortunately, with m68k I get this error:

m68k:  +   M5329AFEE
+arch/m68k/cpu/mcf532x/start.o: In function `_start':
+arch/m68k/cpu/mcf532x/start.S:159:(.text+0x452): relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text.board_init_f section in common/built-in.o

I hope someone can shed some light on what this means. I hope it isn't
depending on the position of code in the image.

f4db6c976c arm: mvebu: Add runtime detection of UART (xmodem) boot-mode
This patch adds runtime detection of the Marvell UART boot-mode (xmodem
protocol). If this boot-mode is detected, SPL will return to the
BootROM to continue the UART booting.

With this patch its now possible, to generate a U-Boot image that
can be booted either from the strapped boot-device (e.g. SPI NOR, MMC,
etc) or via the xmodem protocol from the UART. In the UART case,
the kwboot tool will dynamically insert the UART boot-device type
into the image. And also patch the load address in the header, so
that the mkimage header will be skipped (as its not expected by the
Marvell BootROM).

This simplifies the development for Armada XP / 38x based boards.
As no special images need to be generated by selecting the
MVEBU_BOOTROM_UARTBOOT Kconfig option.

Since the Kconfig option MVEBU_BOOTROM_UARTBOOT is not needed any
more, its now completely removed.

da58dec866 Various Makefiles: Add SPDX-License-Identifier tags

equivalent tag.

b098032387 x86: ifdtool: Support collating microcode into one place
The Intel Firmware Support Package (FSP) requires that microcode be provided
very early before the device tree can be scanned. We already support adding
a pointer to the microcode data in a place where early init code can access.

However this just points into the device tree and can only point to a single
lot of microcode. For boards which may have different CPU types we must
support multiple microcodes and pass all of them to the FSP in one place.

Enhance ifdtool to scan all the microcode, place it together in the ROM and
update the microcode pointer to point there. This allows us to pass multiple
microcode blocks to the FSP using its existing API.

Enable the flag in the Makefile so that this feature is used by default for
all boards.

It is useful to be able to load U-Boot onto a board even if is it already
running EFI. This can allow access to the U-Boot command interface, flexible
booting options and easier development.

The easiest way to do this is to build U-Boot as a binary blob and have an
EFI stub copy it into RAM. Add support for this feature, targeting 32-bit
initially.

Also add a way to detect when U-Boot has been loaded via a stub. This goes
in common.h since it needs to be widely available so that we avoid redoing
initialisation that should be skipped.

Add support for building U-Boot as an EFI application with a .efi suffix.
This can be loaded by EFI provided that EFI has the same bit width (32-

467a40dfe3 powerpc/mpc85xx: SECURE BOOT- NAND secure boot target for P3041
Secure Boot Target is added for NAND for P3041.
For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC.
In case of secure boot, this default address maps to Boot ROM.
The Boot ROM code requires that the bootloader(U-boot) must lie
in 0 to 3.5G address space i.e. 0x0 - 0xDFFFFFFF.

In case of NAND Secure Boot, CONFIG_SYS_RAMBOOT is enabled and CPC is
configured as SRAM. U-Boot binary will be located on SRAM configured
at address 0xBFF00000.
In the U-Boot code, TLB entries are created to map the virtual address
0xFFF00000 to physical address 0xBFF00000 of CPC configured as SRAM.

f3f431a712 Reproducible U-Boot build support, using SOURCE_DATE_EPOCH
In order to achieve reproducible builds in U-Boot, timestamps that are defined
at build-time have to be somewhat eliminated. The SOURCE_DATE_EPOCH environment
variable allows setting a fixed value for those timestamps.

Simply by setting SOURCE_DATE_EPOCH to a fixed value, a number of targets can be
built reproducibly. This is the case for e.g. sunxi devices.

However, some other devices might need some more tweaks, especially regarding
the image generation tools.

4d713be139 kbuild: use relative path more to include Makefile
Prior to this commit, it was impossible to use relative path to
include Makefiles from the top level Makefile because the option
"--include-dir=$(srctree)" becomes effective when Make enters into
sub Makefiles.

To use relative path in any places, this commit moves the option
above the "sub-make" target.

This was imported from Linux (commit a436bb7b8063) and adjusted for
U-Boot.

1fddd7b63c tools/imagetool: remove linker script
Commit a93648d197 introduced linker generated
lists for imagetool which is the base for some host tools (mkimage, dumpimage,
et al.).  Unfortunately some host tool chains do not support the used type of
linker scripts. Therefore this commit broke these host-tools for them, namely
FreeBSD and Darwin (OS/X).

This commit tries to fix this. In order to have a clean distinction between host
and embedded code space we need to introduce our own linker generated list
instead of re-using the available linker_lists.h provided functionality.  So we
copy the implementation used in linux kernel script/mod/file2alias.c which has
the very same problem (cause it is a host tool). This code also comes with an
abstraction for Mach-O binary format used in Darwin systems.

e19db555b4 Kbuild: introduce Makefile in arch/$ARCH/
Introduce a Makefile under arch/$ARCH/ and include it in the
top Makefile (similar to Linux kernel). This allows further
refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.

In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally
after the top config.mk.

3ff291f371 kconfig: convert Kconfig helper script into a shell script
Commit 51148790 added scripts/multiconfig.py written in Python 2
to adjust Kconfig for U-Boot.

It has been hard for Python 3 users because Python 2 and Python 3
are not compatible with each other.

We are not happy about adding a new host tool dependency
(in this case, Python version dependency) for the core build process.
After some discussion, we decided to use only basic tools.

The script may get a bit more unreadable by shell scripting,
but we believe it is worthwhile.

In addition, this commit revives "<board>_config" target that is
equivalent to "<board>_defconfig" for backwards compatibility.
It is annoying to adjust various projects which use U-Boot.

Having such code in scripts/Makefile.build results in the same flags

51148790f2 kconfig: switch to Kconfig
This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.

Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.

Usage:

Run "make <board>_defconfig" to do the board configuration.

It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.

You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.

The generic syntax of configuration targets for SPL, TPL is:

  <target_image>/<config_command>

Here, <target_image> is either 'spl' or 'tpl'
      <config_command> is 'config', 'menuconfig', 'xconfig', etc.

When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)

For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.

By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.

Prior to Kconfig, we used C headers to define a set of configs.

We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

63b4b5bae5 fdt: Add DEV_TREE_BIN option to specify a device tree binary file
In some cases, an externally-built device tree binary is required to be
attached to U-Boot. An example is when using image signing, since in that
case the .dtb file must include the public keys.

Add a DEV_TREE_BIN option to the Makefile, and update the documentation.

Usage is something like:

	make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb

89742924c8 Check that u-boot.bin size looks correct
Check that the image size matches the size we get from u-boot.bin. If it
doesn't, that generally means that some extra sections are being added to
u-boot.bin, meaning that it is not possible to access data appended to
the U-Boot binary. This is used for device tree, so needs to work.

This problem was introduced by commit b02bfc4. By adding a test we can

9262233a96 Makefile: fix clang warnings due to clang support
Building u-boot tools with clang as a host compiler e.g. on
FreeBSD with `gmake HOSTCC=clang CONFIG_USE_PRIVATE_LIBGCC=y tools`
leads to many warnings [1] for every compiler invocation since
commit 598e2d33. Part of mentioned commit imports linux patches:

 - kbuild: LLVMLinux: Adapt warnings for compilation with clang
 - kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang

No version of clang supports the gcc fno-delete-null-pointer-checks
though, but it is only passed to clang. Gcc does not have the clang
specific Qunused-arguments for the target. Furthermore several
warnings are disabled which aren't encountered in u-boot. Since such
a build has worked for quite some time and works after removing these
changes, just remove the clang specific handling to restore normal
building with clang as hostcc.

[1] Actual warnings
-------------------
  GEN     include/autoconf.mk.dep
arm-freebsd-gcc: unrecognized option '-Qunused-arguments'

  HOSTCC  scripts/basic/fixdep
clang: warning: argument unused during compilation:
                '-fno-delete-null-pointer-checks'

2405d09c4c build: support a new image u-boot-dtb.img
In SPL framework, SPL uses u-boot.img to load u-boot.bin.
Here,
    u-boot.img = uImage header + u-boot.bin

To use OF control with a separate devicetree,
u-boot.dtb must be placed right after u-boot.bin.
In this case, u-boot-dtb.bin is generally used.
Here,
    u-boot-dtb.bin = u-boot.bin + u-boot.dtb

We need u-boot-dtb.img to use both SPL framework
and separate OF control at the same time.
    u-boot-dtb.img = uImage header + u-boot-dtb.bin

For example, Zynq boards already define all of
  - CONFIG_SPL
  - CONFIG_OF_CONTROL
  - CONFIG_OF_SEPARATE

So, the support of u-boot-dtb.img is urgent.

cam_enc_4xx: convert to CONFIG_SPL_MAX_FOOTPRINT

replaced CONFIG_SPL_MAX_SIZE by CONFIG_SPL_MAX_FOOTPRINT. However,
CONFIG_SPL_MAX_SIZE is used in the Makefile for padding the SPL
when preparing an u-boot.ais image. By removing CONFIG_SPL_MAX_SIZE
said commits broke the ais image of the da850evm and cam_enc_4xx
configurations.

This patch converts the u-boot.ais target to use CONFIG_SPL_PAD_TO
instead of CONFIG_SPL_MAX_SIZE for padding the SPL and adds
a #define CONFIG_SPL_PAD_TO where it is required.

Using __DATE__, __TIME__ would make the build non-deterministic.

U_BOOT_TIME in include/generated/timestamp_autogenerated.h instead.

This commit has been imported from Linux Kernel,
which should be applied to U-Boot too:

    commit fe7c36c7bde12190341722af69358e42171162f3

    Makefile: Build with -Werror=date-time if the compiler supports it

    GCC 4.9 and newer have a new warning -Wdate-time, which warns on any use
    of __DATE__, __TIME__, or __TIMESTAMP__, which would make the build
    non-deterministic.  Now that the kernel does not use any of those
    macros, turn on -Werror=date-time if available, to keep it that way.

    The kernel already (optionally) records this information at build time
    in a single place; other kernel code should not duplicate that.

794d5f5540 Revert "build: Use filechk rules to create and update u-boot.lds"
This reverts commit a8b993eb81.

Commit a8b993eb claims it fixes u-boot.lds rule by replacing
$(call if_changed) with $(call filechk).

But the problem had already been fixed by commit 395e60cd
a few days before commit a8b993eb was posted.

There is no reason to apply commit a8b993eb. What is worse is
$(call filechk) is too strong to fix the problem and looks weird.

Date of the two patches:

[1] commit 395e60cdc2

    AuthorDate: Wed Apr 9 20:10:43 2014 +0900
    Commit:     Tom Rini <trini@ti.com>
    CommitDate: Fri Apr 11 10:08:42 2014 -0400
replaces $(call if_changed) -> $(call if_changed_dep)

[2] commit a8b993eb81

    AuthorDate: Tue Apr 15 16:09:37 2014 -0500

    CommitDate: Fri Apr 18 16:14:16 2014 -0400

A conflict must have happened when applying [2], but somehow it was
applied, sadly.

a8b993eb81 build: Use filechk rules to create and update u-boot.lds
Prior to this patch, the top-level linker script u-boot.lds
used a simple $(call if_changed) check when generated.
That mechanism misses cases where a possible include file
change induces a change in the u-boot.lds too.

This patch converts it to a stronger check using ($call filechk)
that will also notice differences in file contents and
will catch changes due to pre-processing as well.

1a9df13d5b arm: mxs: Add support for generating signed BootStream
This patch adds the groundwork for generating signed BootStream, which
can be used by the HAB library in i.MX28. We are adding a new target,
u-boot-signed.sb , since the process for generating regular non-signed
BootStream is much easier. Moreover, the signed bootstream depends on
external _proprietary_ _binary-only_ tool from Freescale called 'cst',
which is available only under NDA.

To make things even uglier, the CST or HAB mandates a kind-of circular
dependency. The problem is, unlike the regular IVT, which is generated
by mxsimage, the IVT for signed boot must be generated by hand here due
to special demands of the CST. The U-Boot binary (or SPL binary) and IVT
are then signed by the CST as a one block. But here is the problem. The
size of the entire image (U-Boot, IVT, CST blocks) must be appended at
the end of IVT. But the size of the entire image is not known until the
CST has finished signing the U-Boot and IVT. We solve this by expecting
the CST block to be always 3904B (which it is in case two files, U-Boot
and the hand-made IVT, are signed in the CST block).

CST has finished signing the U-Boot and IVT. We solve this by expecting
the CST block to be always 3904B (which it is in case two files, U-Boot
and the hand-made IVT, are signed in the CST block).

4642e0022b Kbuild: allow building tools without board configuration
Prior to Kbuild, U-Boot could build under tools/ directory
withour configuring for a specific board.

That feature was lost when switching to Kbuild.

This patch revives it again by adding a make target "tools-only".

Usage:
  $ make tools-only

Neither board configuration nor cross compiler are required to
build host tools.

5a449d75bc kbuild: create a build directory automatically for out-of-tree build
Prior to Kbuild, the build system created a build directory,
when it did not exist, for out-of-tree build.

This feature was dropped when we switched to Kbuild
because many of lines in makefiles were copied from Linux Kernel.
(In Linux Kernel, we have to create a build directory by ourselves
before starting build.)

That feature seems worth reviving for less typing
even if our code and Linux Kernel diverge.

026f9cf24f kbuild: improve Kbuild speed
Kbuild brought about many advantages for us but a significant
performance regression was reported by Simon Glass.

After some discussions and analysis, it turned out
its main cause is in $(call cc-option,...).

Historically, U-Boot parses all config.mk
(arch/*/config.mk and board/*/config.mk)
every time descending into subdirectories.
That means cc-options are evaluated over and over again.

$(call cc-option,...) is useful but costly.
So we want to evaluate them only in ./Makefile
and spl/Makefile and export compiler flags.

This commit changes the build system as follows:

  - Modify scripts/Makefile.build to not include config.mk
    Instead, add $(PLATFORM_CPPFLAGS) to asflags-y, ccflags-y,
    cppflags-y.

  - Export many variables
    Going forward, Kbuild will not parse config.mk files
    when it descends into subdirectories.
    If we want to set variables in config.mk and use them
    in subdirectories, they must be exported.

    This is the list of variables to get exported:
      PLATFORM_CPPFLAGS
      CPUDIR
      BOARDDIR
      OBJCOPYFLAGS
      LDFLAGS
      LDFLAGS_FINAL
        (used in nand_spl/board/*/*/Makefile)
      CONFIG_STANDALONE_LOAD_ADDR
        (used in examples/standalone/Makefile)
      SYM_PREFIX
        (used in examples/standalone/Makefile)
      RELFLAGS
        (used in examples/standalone/Makefile)

  - Delete CPPFLAGS
    This variable has been replaced with PLATFORM_CPPFLAGS

  - Copy gcclibdir from example/standalone/Makefile
    to arch/sparc/config.mk
    The reference in CONFIG_STANDALONE_LOAD_ADDR must be
    resolved before it is exported.

cd2e46cb38 kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCC
Before this commit, USE_PRIVATE_LIBGCC was defined in
arch-specific config.mk and referenced in
arch/$(ARCH)/lib/Makefile.

We are not happy about parsing config.mk again and again.
We have to keep the same behavior with a different way.

By adding "CONFIG_" prefix, this macro appears
in include/autoconf.mk, include/spl-autoconf.mk.
(And treating USE_PRIVATE_LIBGCC as CONFIG macro
is reasonable enough.)

Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
in arch/arm/cpu/arm720t/tegra*/config.mk,
whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.

It means Tegra enables PRIVATE_LIBGCC only for SPL.
We can describe the same behavior by adding

  #ifdef CONFIG_SPL_BUILD
  # define CONFIG_USE_PRIVATE_LIBGCC
  #endif

to include/configs/tegra-common.h.

U-Boot has compelled all boards to have

Sometimes it does not seem suitable for some boards,
for example Sandbox. (Is it a board?)

And arcangel4 board has nothing to compile

db5b339cca kbuild: add "cross_tools" target to build tools for the target
Programs in tools/ directory are usually built for the host.
But some of them (mkimage, dumpimge, gen_eth_addr, etc.) are
useful on the target OS too.

Actually, prior to Kbuild, U-Boot could build tools for
the target like follows:

  $ make <target_board>_config
  $ export CROSS_COMPILE=<cross_gcc_prefix>
  $ make HOSTCC=${CROSS_COMPILE}gcc HOSTSTRIP=${CROSS_COMPILE}strip tools

In Kbuild, we can no longer replace HOSTCC at the command line.

In order to get back that feature, this commit adds "cross-tools" target.

Usage:

  Build tools for the host
  $ make CROSS_COMPILE=<cross_gcc_prefix> tools

  Build tools for the target
  $ make CROSS_COMPILE=<cross_gcc_prefix> cross_tools

Besides, "make cross_tools" strip tools programs because we
generally expect smaller storages on embedded systems.

Before this commit, make terminated with an error
where is shouldn't under some condition.

This bug happened when we built a board unsupporting
generic board right after building with generic board.

For example, the following sequence failed.
(harmony uses generic board but microblaze-generic does not
support it)

  $ make harmony_config
  Configuring for harmony board...
  $ make CROSS_COMPILE=arm-linux-gnueabi-
    [ Build succeed ]
  $ make microblaze-generic_config
  Configuring for microblaze-generic board...
  $ make CROSS_COMPILE=microblaze-linux-
  Makefile:488: *** Your architecture does not support generic board.
  Please undefined CONFIG_SYS_GENERIC_BOARD in your board config file.  Stop.

We had to do "make clean" before building the microblaze board.

This commit fixes this unconvenience.

Move generic board sanity check to "prepare1" target,
which is run after generation of include/autoconf.mk.

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__.

7424145f30 kbuild: consolidate version and timestamp headers generation
- Generate include/generated/{timestamp.h, version.h}
   more simply by using filechk rule.

 - Add $(UBOOTRELEASE) variable and re-write u-boot.imx rule
   more simply.

 - Rename U_BOOT_VERSION in Makefile to UBOOTVERSION

   Before this commit, the same variable name, "U_BOOT_VERSION"
   was used for two different strings.

   One of them was defined in Makefile.
   It takes the form like "2014.01-rc1" and used in
   makefiles and script files.

   The other is defined in include/generated/version.h
   It takes the form like "U-Boot 2014.01-rc1-00010-gbe6d426-dirty"
   and used in C and Aseembler.

   It is confusing when grepping the source tree. So, this commit
   renames the former to UBOOTVERSION.

53bca5ab6a kbuild: support simultaneous board configuration and "make all"
This commit fixes two problems:

[1] We could not do board configuration and "make all"
    in one command line.

For example, the following did not work as we expect:
  $ make sandbox_config all
  Configuring for sandbox board...
  make: Nothing to be done for `all'.

[2] mixed-target build did not work with -j option

For example, the following did not work:
  $ make -j8 sandbox_config u-boot
  Makefile:481: *** "System not configured - see README".  Stop.
  make: *** [u-boot] Error 2
  make: *** Waiting for unfinished jobs....
  Configuring for sandbox board...

Going forward, we can do
  $ make -j8 sandbox_config all

This is the same as
  $ make sandbox_config
  $ make -j8

6825a95b0b kbuild: use Linux Kernel build scripts
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 obj

We 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.

9e4140329e kbuild: change out-of-tree build
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-boot

Here, $(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 <sub-dir>" 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=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

f6322eb7af Makefile: move some variable definitions to the top Makefile
This commit moves some variable definitions from config.mk
to the top Makefile:

  - HOSTCC, HOSTCFLAGS, HOSTLDFLAGS
  - AS, LD, CC, CPP, etc.
  - SHELL (renamed to CONFIG_SHELL)

I'd like to slim down config.mk file
because it is included from all recursive make.
It is redundant to re-define the variables
every time descending into sub directories.
We should rather define them at the top Makefile
and export them.

U-Boot makefiles has been used "SHELL" variable to store shell
chosen for the user, whereas Linux Kernel uses "CONFIG_SHELL".

We should never use "SHELL" variable because it is
a special variable for GNU Make.
Changing SHELL may cause unpredictable side effects
whose root cause is usually difficult to find.
We should use a generic variable name "CONFIG_SHELL".

We should not use the syntax as follows either:

    rm -f $(obj)tools/env/{fw_printenv,fw_setenv}

This depends on "bash" although GNU Make generally
invokes "sh" to run the each rule.

f4dc714aaa arm64: Turn u-boot.bin back into an ELF file after relocate-rela
While performing relocations on u-boot.bin should be good enough for
booting on real hardware, some simulators insist on booting an ELF file
(and yet don't perform ELF relocations), so convert the relocated
binary back into an ELF file.  This can go away in the future if we
change relocate-rela to operate directly on the ELF file, or if and
when we stop caring about a simulator with this restriction.

8137af19e7 arm64: Add tool to statically apply RELA relocations
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.

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.

755e08f0e5 post: descend only when CONFIG_HAS_POST is defined
All objects under post/ directory are enabled by CONFIG_HAS_POST.
(post/tests.o is enabled by CONFIG_POST_STD_LIST.
But CONFIG_POST_STD_LIST depends on CONFIG_HAS_POST.)

We can move CONFIG_HAS_POST switch to the top Makefile.

8e9a6cb169 Makefile: delete a make rule of $(LDSCRIPT)
$(LDSCRIPT) is a source file, not a generated file.
We do not need a make rule of $(LDSCRIPT).

And one more trivial fix:
$(obj)/u-boot should not dierectly depend on $(LDSCRIPTS).

a8c075414a Makefile: use two double-quotations as a pair
Some editors such as Emacs can highlight source files.
But their parser algorithm is not perfect.

If you use one double-quotation alone, some editor cannot
handle it nicely and mark source lines as a string by mistake.

It is preferable to use two double-quotations as a pair.

65947ab4c9 Makefile: Do not create empty autoconf.mk on error
The build rules of
  - include/autoconf.mk.dep
  - include/autoconf.mk
  - include/spl-autoconf.mk
  - include/tpl-autoconf.mk
were not nice.

They created empty files (which are never updated)
if an error occurs during preprocessing.

a804b5ce2d Add dumpimage, a tool to extract data from U-Boot images
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.
