      powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260 · 58dac327
      Masahiro Yamada authored 
      
Before this commit, CONFIG_MPC8260 and CONFIG_8260
were used mixed-up.

All boards with mpc8260 cpu defined both of them:
  - CONFIG_MPC8260 was defined in board config headers
      and include/common.h
  - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk

We do not need to have both of them.
This commit keeps only CONFIG_MPC8260.

This commit does:
 - Delete CONFIG_8260 and CONFIG_MPC8260 definition
   in config headers and include/common.h
 - Rename CONFIG_8260 to CONFIG_MPC8260
    in arch/powerpc/cpu/mpc8260/config.mk.
 - Rename #ifdef CONFIG_8260 to #ifdef CONFIG_MPC8260

      kbuild: improve Kbuild speed · 026f9cf2
      Masahiro Yamada authored 
      
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.

      kbuild: use Linux Kernel build scripts · 6825a95b
      Masahiro Yamada authored 
      
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.

      kbuild: change out-of-tree build · 9e414032
      Masahiro Yamada authored 
      
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.

      Makfile: move suffix rules to Makefile.build · 5651ccff
      Masahiro Yamada authored 
      
This commit moves suffix rules from config.mk
to scripts/Makefile.build, which will allow us
to switch smoothly to real Kbuild.

Note1:
post/lib_powerpc/fpu/Makefile has
its own rule to compile C sources.
We need to tweak it to keep the same behavior.

Note2:
There are two file2 with the same name:
arch/arm/lib/crt0.S and eamples/api/crt0.S.
To keep the same build behavior,
examples/api/Makefile also has to be treaked.

      ARM: fix the standalone programs · a5a42eec
      Jeroen Hofstee authored 
      
The standalone programs do not use the api calls, but rely
directly on u-boot variable gd->jt for the jump table. Commit
fe1378a9 - "ARM: use r9 for gd" changed the register holding
the address of gd, but the assembly code in the standalone
examples was not updated accordingly. This broke the programs
on ARM relying on the jumptable in the v2013.10 release.
This patch unbricks them by using the correct register.

      Revert "standalone-examples: support custom GCC lib" · 8386ca8b
      Tom Rini authored 
      
After further testing, this patch has two problems.  First,
examples/standalone/Makefile was already inherting PLATFORM_LIBS from
the top-level Makefile so this lead to duplicating the private libgcc.
Second, currently the private libgcc has a reference to 'hang' that is
not being fulfilled.

This reverts commit 4412db46.

      Reduce build times · cca4e4ae
      Wolfgang Denk authored 
      
U-Boot Makefiles contain a number of tests for compiler features etc.
which so far are executed again and again.  On some architectures
(especially ARM) this results in a large number of calls to gcc.

This patch makes sure to run such tests only once, thus largely
reducing the number of "execve" system calls.

Example: number of "execve" system calls for building the "P2020DS"
(Power Architecture) and "qong" (ARM) boards, measured as:
	-> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board>
	-> grep execve /tmp/foo | wc -l

	Before: After:	Reduction:
==================================
P2020DS 20555	15205	-26%
qong	31692	14490	-54%

As a result, built times are significantly reduced, typically by
30...50%.
