* kbuild: standalone: simplify clean-filesMasahiro Yamada2014-09-161-1/+1
| | | | | | | Files added $(extra-) are removed by "make clean". Besides, wildcard "*.srec *.bin" is simpler. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* standalone: use GCC_VERSION defined in compiler-gcc.hMasahiro Yamada2014-09-161-5/+2
| | | | | | | | | | | | Now GCC_VERSION is defined in include/linux/compiler-gcc.h (with a little different definition). Use it and delete the one in examples/standlone/stub.c. This should work on Clang too because __GNUC__, __GNUC_MINOR__, __GNUC_PATCHLEVEL__ are also defined on Clang.

* examples: select libgcc for non-default architectureAlexey Brodkin2014-05-231-3/+1
| | | | | | | | | | | | | | | | | | | In case of multilib-enabled toolchains if default architecture differ from the one examples are being built for linker will fail to link example object files with libgcc of another (non-compatible) architecture. Interesting enough for years in main Makefile we used CFLAGS/c_flags for this but not for examples. So fixing it now.

* powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260Masahiro Yamada2014-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Wolfgang Denk <wd@denx.de>
* kbuild: improve Kbuild speedMasahiro Yamada2014-03-071-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 buildMasahiro Yamada2014-02-192-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The standalone programs do not use the api calls, but rely directly on u-boot variable gd->jt for the jump table. Commit fe1378a - "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.

| | | | | | | | | | | | After further testing, this patch has two problems.

* Reduce build timesWolfgang Denk2011-11-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%.
