mips: move CONFIG_MIPS{32, 64} definition to config.mk

2014-03-07T15:59:06Z

All mips32 boards define CONFIG_MIPS32 in config headers except malta boards which define it in boards.cfg. We can consolidate them by defining it in arch/mips/cpu/mips32/config.mk. CONFIG_MIPS64 definition can be moved to arch/mips/cpu/mips64/config.mk as well. Signed-off-by: Masahiro Yamada Cc: Daniel Schwierzeck Acked-by: Daniel Schwierzeck

config.mk: specify the exact path to standalone linker script

2014-03-07T15:59:06Z

We want to change the build system to include config.mk only from ./Makefile and spl/Makefile. We must prepare for that in this commit. $(src) is a moving target and not handy for our purpose. We must replace it with a fixed path. Signed-off-by: Masahiro Yamada

kbuild: change out-of-tree build

2014-02-19T16:07:50Z

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 " 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=" syntax for descending into sub-directories. (We can write it like "make $(obj)=" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada Tested-by: Gerhard Sittig

MIPS: add dynamic relocation support

2013-02-12T21:22:13Z

The code handles relocation entries with the following relocation types only: mips32: R_MIPS_REL32 mips64: R_MIPS_REL+R_MIPS_64 xburst: R_MIPS_REL32 Other relocation entries are skipped without processing. The code must be extended if other relocation types must be supported. Add -pie to LDFLAGS_FINAL to generate the .rel.dyn fixup table, which will be applied to the relocated image before transferring control to it. The CONFIG_NEEDS_MANUAL_RELOC is not needed after the patch, so remove that as well. Signed-off-by: Gabor Juhos Signed-off-by: Daniel Schwierzeck

MIPS: start.S: use symbol __image_copy_end for U-Boot image relocation

2013-02-12T21:22:13Z

Use the newly introduced symbol __image_copy_end as end address for relocation of U-Boot image. This is needed for dynamic relocation added in later patches. This patch obsoletes the symbols uboot_end and uboot_end_data which are removed. Signed-off-by: Daniel Schwierzeck

MIPS: start.S: optimize BSS initialization

2013-02-12T21:22:13Z

Get the start and end address for clearing BSS from the newly introduced symbols __bss_start and __bss_end. After GOT is relocated, those symbols are already pointing to the correct addresses. Also optimize the loop by moving the address incrementation to the delay slot to avoid the initial sub instruction. Signed-off-by: Daniel Schwierzeck
