[U-Boot] [PATCH] mips: move CONFIG_MIPS{32, 64} definition to config.mk
by Masahiro Yamada 05 Mar '14

05 Mar '14

All mip32 boards define CONFIG_MIPS32 in config headers except malta board which defines 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.

Actually the struct only used in clock configuration. By doing this, we won't need to have the malloc.
