* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-15/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Yamada2014-02-19-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Makfile: move suffix rules to Makefile.buildMasahiro Yamada2014-02-19-1/+1
| | | | | | | | | | | | | | | | | | | 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.

* post: descend only when CONFIG_HAS_POST is definedMasahiro Yamada2013-12-13-14/+14

* post/lib_powerpc/multi.c: fix stack overflow errorWolfgang Denk2011-12-23-4/+4
| | | | | | | | | | | | | | | | | | | The code and comment disagreed: the comment claimed that r6...r31 were copied, and consequently the arrays for "src" and "dst" were declared with 26 entries, but the actual code ("lmw r5,0(r3)" and "stmw r5,0(r4)") copied _27_ words (r5 through r31), which resulted in false "POST cpu Error at multi test" messages. Fix the comment and the array sizes.

* PPC: fix "Warning: FOO uses hard float, BAR uses soft float".Wolfgang Denk2011-12-23-2/+156
| | | | | | | | | | | | | | | | | | | | | | | | | | | It appears that with recent versions of GCC the explicit "-mhard-float" command line option takes precedence over the ``asm(".gnu_attribute 4, 2");'' in the source file, so this no longer helps to avoid the warnings we get when linking code that uses FP instructions with other code that was built using soft-float. We can remove the ".gnu_attribute" (which appears to carry no other information, at least so far) from the object files, but we also have to make sure we don't pull in the __gcc_qsub() and __gcc_qmul() functions from the standard libgcc, as these would again "infect" our linking. We copy this code from: gcc-4.2.2/gcc/config/rs6000/darwin-ldouble.c This old version was chosen because it was still available under a compatible license (GCC v2+). The file was stripped down to the needed parts, and reformatted so it passes checkpatch with only one warning (do not add new typedefs).

* powerpc: Fix FPU post related link warningsKumar Gala2011-01-25-16/+16
| | | | | | | | | | | | | | | | | | | | | | If we built POST on PPC's that didn't enable CONFIG_SYS_POST_FPU we'd get the following warning with newer toolchains: powerpc-linux-gnu-ld: Warning: lib_powerpc/fpu/libpostpowerpcfpu.o uses hard float, libpost.o uses soft float We actually worked around this sometime ago with the following commit: commit ce82ff05388b5ddafdf6082ef0776cce72c40b1c Author: Yuri Tikhonov <yur@emcraft.com> Date: Sat Dec 20 14:54:21 2008 +0300 FPU POST: fix warnings when building with 2.18 binutils However, this only took into effect if CONFIG_SYS_POST_FPU was enabled. We can simply move the GNU_FPOST_ATTR out of the CONFIG_SYS_POST_FPU ifdef block to address the issue. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-0/+4844
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
