Subject: asm-generic/unaligned.h: dynamic default unaligned accesses
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3adc1fda38a6aacd4aaf3c2c9cc62a1e69e6de17;p=u-boot.git

asm-generic/unaligned.h: dynamic default unaligned accesses

This is based on the asm-arm/unaligned.h, but made generic so all arches
that cannot do unaligned accesses can utilize it.
