Subject: ARM:asm:io.h use static inline
X-Git-Tag: v2014.10-rc2~47
X-Git-Url: http://git.denx.de/?p=u-boot.git;a=commitdiff_plain;h=8863aa5c984460ce1112d8db895cbf8b13a6ac9d
ARM:asm:io.h use static inline
When compiling u-boot with W=1 the extern inline void for
read* is likely causing the most noise. gcc / clang will
warn there is never a actual declaration for these functions.
Instead of declaring these extern make them static inline so
it is actually declared.
