[PATCH] powerpc: clean up binutils version check

The checkbin in arch/powerpc/Makefile errors out if ld <= 2.24. So, the requirement on PPC is binutils >= 2.25. It is cleaner to specify it in scripts/min-tool-version.sh. If binutils < 2.25 is used, the toolchain check will fail in the Kconfig stage going forward. Since binutils >= 2.25 is alread

[PATCH] powerpc/boot: Explicitly disable usage of SPE instructions

uImage boot wrapper should not use SPE instructions, like kernel itself. Boot wrapper has already disabled Altivec and VSX instructions but not SPE. Options -mno-spe and -mspe=no already set when compilation of kernel, but not when compiling uImage wrapper yet. Fix it. Cc: sta...@vger.kernel.org S

[PATCH v2] powerpc/boot: Don't always pass -mcpu=powerpc when building 32-bit uImage

For 32-bit uImage try to use CONFIG_TARGET_CPU option for -mcpu. This fixes following compiler error when building kernel with powerpc e500 SPE capable cross compilers: BOOTAS arch/powerpc/boot/crt0.o powerpc-linux-gnuspe-gcc: error: unrecognized argument in option ‘-mcpu=powerpc’ powerp

[PATCH] powerpc: dts: turris1x.dts: Fix labels in DSA cpu port nodes
