      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%.

      examples: api: allow build with private libgcc · 349e83f0
      Che-liang Chiou authored
      The examples/api is not configured with USE_PRIVATE_LIBGCC.  This makes
      building examples/api break on certain boards that do not/cannot use the
      public libgcc.
      
      Nevertheless, this patch has to also touch the top-level Makefile to fix
      this problem because the current top-level Makefile does not specify
      libgcc as a prerequisite of examples/api, and explicitly builds
      examples/api _before_ libgcc.
      
      For testing this patch, I added the following to configs/seaboard.h and
      ran demo.bin on a Seaboard.
      
      +#define CONFIG_API
      +#define CONFIG_SYS_MMC_MAX_DEVICE 2
      +#define CONFIG_CMD_NET
      +#define CONFIG_NET_MULTI

      Fix variable flavor in examples/standalone/Makefile · 0da43893
      Che-liang Chiou authored
      GNU Makefile have two flavors of variables, recursively expanded that is
      defined by using '=', and simply expanded that is defined by using ':='.
      
      The bug is caused by using recursively expanded flavor for BIN and SREC.
      As you can see below, they are prepended by $(obj) twice.
      
      We can reproduce this bug with a simplified version of this Makefile:
      $ cat >Makefile <<\EOF
      obj := /path/to/obj/
      ELF := hello_world
      
      BIN_rec = $(addsuffix .bin,$(ELF))      # recursively expanded
      BIN_sim := $(addsuffix .bin,$(ELF))     # simply expanded
      
      ELF := $(addprefix $(obj),$(ELF))
      BIN_rec := $(addprefix $(obj),$(BIN_rec))
      BIN_sim := $(addprefix $(obj),$(BIN_sim))
      
      show:
      	@echo BIN_rec=$(BIN_rec)
      	@echo BIN_sim=$(BIN_sim)
      
      .PHONY: show
      EOF
      $ make show
      BIN_rec=/path/to/obj//path/to/obj/hello_world.bin
      BIN_sim=/path/to/obj/hello_world.bin
