[PATCH] ppc32: export cacheable_memcpy()

e8834801 · Eugene Surovegin <[email protected]> · 2005-09-03 15:55:54 -07:00

Add declaration and cacheable_memcpy().  I'll be needing this function in
new 4xx EMAC driver I'm going to submit to netdev soon.

IMHO, the better place for the declaration would be asm-powerpc/string.h,
unfortunately, ppc64 doesn't have this function, so asm-ppc/system.h is the
next best place.
