kbuild: use SoC-specific CONFIG to descend into SoC directory

2014-11-23T11:49:02Z

Use "obj-$(CONFIG_FOO) += foo/" where it is possible. Signed-off-by: Masahiro Yamada

kbuild: Descend into SOC directory from CPU directory

2014-11-23T11:49:02Z

Some CPUs of some architectures have SOC directories. At present, the build system directly descends into SOC directories from the top Makefile, but it should generally descend into each directory from its parent directory. Signed-off-by: Masahiro Yamada

include: move various macros to include/linux/kernel.h

2014-11-20T16:28:25Z

U-Boot has imported various utility macros from Linux scattering them to various places without consistency. In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point. Signed-off-by: Masahiro Yamada

MIPS: add .padding section to linker script

2014-11-01T17:18:05Z

Commit 79fd7e649e287228a1445820a72f7dd33baedb96 MIPS: always keep all sections in u-boot ELF binary. Always keep all sections in u-boot ELF binary. Move all unneeded sections after _end to avoid allocating space in the final binary. Also remove .deadcode section which is now obsolete. removed section .deadcode because the original symptoms were not visible anymore. Unfortuneatly the binutils bug still exists. The size of .rel.dyn section is often bigger than needed for all entries. But objcopy only allocates space as much as required for all reloc entries. Thus there is a gap between the last entry and __rel_dyn_end in u-boot.bin. If u-boot is booted from RAM (e.g. in SPL scenarios) that area could contain garbage data which could lead to CPU exceptions during relocation.

MIPS: refactor setting of compiler options

2014-11-01T17:18:05Z

Refactor and unify all compiler settings in arch/mips/config.mk. Also add tune flags for each supported CPU type. Signed-off-by: Daniel Schwierzeck

MIPS: kconfig: merge targets qemu_mips and qemu_mips64

2014-11-01T17:18:04Z

Now the user can separately select the CPU type. Thus the targets qemu_mips and qemu_mips64 can be merged to a single target. Signed-off-by: Daniel Schwierzeck

MIPS: kconfig: globally define CONFIG_SYS_CPU for MIPS

2014-11-01T17:18:04Z

Now the user can select the CPU type for each target. Thus CONFIG_SYS_CPU could be set globally. Signed-off-by: Daniel Schwierzeck

MIPS: kconfig: add options for CPU type select

2014-11-01T17:18:03Z

Add new Kconfig option to let the user select the targets CPU type. Each target have to select SUPPORTS_CPU_MIPS[32,64]_R[1,2] to indicate which CPU types are supported. Signed-off-by: Daniel Schwierzeck

MIPS: kconfig: add options for endianess select

2014-11-01T17:17:22Z

Add new Kconfig option to let the user select the targets endianess. Each target have to select SUPPORTS_BIG_ENDIAN and/or SUPPORTS_LITTLE_ENDIAN to indicate which endianess is supported. Signed-off-by: Daniel Schwierzeck

mips: enable CONFIG_USE_PRIVATE_LIBGCC by default

2014-10-23T17:19:15Z

Without the private libgcc, we need a full multilib toolchain with different libgcc or multiple toolchains to build all BE/LE and hard-float/soft-float variants of MIPS boards. That is not feasible. This commit allows us to build all the MIPS boards with a single kernel.org toolchain: https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/ x86_64-gcc-4.9.0-nolibc_mips-linux.tar.xz This change sounds reasonable for most users. If necessary, you can disable this option via "make menuconfig" or friends. Signed-off-by: Masahiro Yamada Acked-by: Daniel Schwierzeck
