Subject: asm-generic/io.h: add reads[bwl]/writes[bwl] helpers
X-Git-Tag: upstream/snapshot3+hdmi~12086^2~46
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=efb2d31c1c62de9a0e42b2b1981d1a90fc0b4618;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

asm-generic/io.h: add reads[bwl]/writes[bwl] helpers

A bunch of arches define reads[bwl]/writes[bwl] helpers for accessing
memory mapped registers.  Since the Blackfin ones aren't specific to
Blackfin code, move them to the common asm-generic/io.h for people.
