I realized that ARM uses the generic memmove() implementation which is
rather slow. This series adds the assembler optimized version for ARM.
The corresponding recent Linux code doesn't fit into barebox anymore, so
to merge the code the surroundings have to be updated first, hence the
series is bigger than I like it to be.

Sascha Hauer (10):
ARM: Use optimized reads[bwl] and writes[bwl] functions
ARM: rename logical shift macros push pull into lspush lspull
ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+
ARM: update lib1funcs.S from Linux
ARM: update findbit.S from Linux
ARM: update io-* from Linux
ARM: always assume the unified syntax for assembly code
ARM: update memcpy.S and memset.S from Linux
lib/string.c: export non optimized memmove as __default_memmove
ARM: add optimized memmove
