f494e0a184 kbuild: refactor some makefiles
[1] Move driver/core/, driver/input/ and drivers/input/ entries
    from the top Makefile to drivers/Makefile

[2] Remove the conditional by CONFIG_DM in drivers/core/Makefile
    because the whole drivers/core directory is already selected
    by CONFIG_DM in the upper level

[3] Likewise for CONFIG_DM_DEMO in drivers/demo/Makefile

[4] Simplify common/Makefile - both CONFIG_DDR_SPD and
    CONFIG_SPD_EEPROM are boolean macros so they can directly
    select objects

f458e3559b kconfig: fix a bug of "make config"
Since 3ff291f371
(kconfig: convert Kconfig helper script into a shell script),
"make config" is not working because of a missing '$' before '(Q)'.

Besides, "make config" should be invoked via scripts/multiconfig.sh
to avoid a warning message:
Kconfig:11:warning: environment variable KCONFIG_OBJDIR undefined

3b61297024 kbuild: force to define __UBOOT__ in all the C sources
U-Boot has imported various source files from other projects,
mostly Linux.

Something like

  #ifdef __UBOOT__
    [ modification for U-Boot ]
  #else
    [ original code ]
  #endif

is an often used strategy for clarification of adjusted parts,
that is, easier re-sync in future.

Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.

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.

e773440425 kbuild: sync mixed targets handling with Linux 3.16
"make %_config all" was supported for the first time in U-Boot:
  commit 53bca5ab
  kbuild: support simultaneous board configuration and "make all"

Surprisingly it had not been working in Linux Kernel for a long time.

So I sent back the patch to the Linux Kbuild community and it was
accepted with a little code improvement, at commit 9319f453.

Now, you can do "make defconfig all" or "make %_defconfig all"
in Linux too.

This commit updates some scripts to fill the code-diff
between Linux and U-Boot.

6419e14492 kbuild: move extra gcc checks to scripts/Makefile.extrawarn
This commit was imported from Linux Kernel:
commit a86fe353 written by me.

W=... provides extra gcc checks.

Having such code in scripts/Makefile.build results in the same flags
being added to KBUILD_CFLAGS multiple times becuase
scripts/Makefile.build is invoked every time Kbuild descends into
the subdirectories.

Since the top Makefile is already too cluttered, this commit moves
all of extra gcc check stuff to a new file scripts/Makefile.extrawarn,
which is included from the top Makefile.

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.

"tags" and "TAGS" are not part of the Makefile build targets and

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

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.

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.

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
    Author:     Jon Loeliger <jon.loeliger@oracle.com>
    AuthorDate: Tue Apr 15 16:09:37 2014 -0500
    Commit:     Tom Rini <trini@ti.com>
    CommitDate: Fri Apr 18 16:14:16 2014 -0400
replaces $(call if_changed) -> $(call filechk)

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).

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.

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.

  acadia_nand
  bamboo_nand
  canyonlands_nand
  glacier_nand
  haleakala_nand
  kilauea_nand
  rainier_nand
  sequoia_nand

331b45fb70 kbuild: Fix a false error of generic board support
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.

  $ make -j8 sandbox_config u-boot
  Makefile:481: *** "System not configured - see README".  Stop.
  make: *** [u-boot] Error 2
  make: *** Waiting for unfinished jobs....

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.

2b3c9d3ddd Makefile: move more flags to the top Makefile
Before this commit, most of compiler flags were defined in config.mk.
But it is redundant because config.mk is included from all recursive make.

This commit moves many complier flags to the top Makefile
and export them.
And we use new vaiarables to store them:
KBUILD_CPPFLAGS, KBUILD_CFLAGS, KBUILD_AFLAGS.
This will allow us to switch more smoothly to Kbuild.

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.

57270260ad Makefile: fix broken pipe error for lcd4_lwmon5 board
Before this commit, a broken pipe error sometimes happened
when building lcd4_lwmon5 board with Buildman.

This commit re-writes build rules of
u-boot.spr and u-boot-img-spl-at-end.bin
more simply without using a pipe.

Besides fixing a broken pipe error,
this commit gives us other advantages:

  - Do not generate intermidiate files, spl/u-boot-spl.img
    and spl/u-boot-spl-pad.img for creating u-boot.spr

  - Do not generate an intermidiate file, u-boot-pad.img
    for creating u-boot-img-spl-at-end.bin

Such intermidiate files were not deleted by "make clean" or "make mrpropr".
Nor u-boot-pad.img was ignored by git.

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.

71f84ef073 ARM: imx-common: convert makefiles to Kbuild style
Multiple targets are included in arch/arm/imx-common/Makefile
In order to refactor it,
we need to tweak Makefile and spl/Makefile.

ce28d7ac6d Makefile: prepare for using Kbuild-style Makefile
Every makefile in sub directories has common lines
at the top and the bottom.
This commit pushes the common parts into script/Makefile.build.

Going forward sub-makefiles only need to describe this part:

    COBJS := ...
    COBJS += ...
    SOBJS := ...

But using obj-y is preferable to prepare for switching to Kbuild.

The conventional (non-Kbuild) Makefile style is still supported.
This is achieved by greping the Makefile before entering into it.
U-Boot conventional sub makefiles always include some other makefiles.
So the build system searches a line beginning with "include" keyword
in the makefile in order to distinguish which style it is.
If the Makefile include a "include" line, we assume it is a conventional
U-Boot style. Otherwise, it is treated as a Kbuild-style makefile.

With this tweak, we can switch sub-makefiles
from U-Boot style to Kbuild style little by little.

obj-y := foo/
syntax (descending into the sub directory) is not supportd yet.
It will be implemented in the upcomming commit.
