[U-Boot] [RESEND][PATCH 06/24] sh4: cache: move exported cache manipulation functions into cache.c

Vladimir Zapolskiy
2016-11-27T22:15:18Z

No functional change, moving cache manipulation functions into cache.c
allows to collect all of them in a single location and as a pleasant
side effect cache_control() function can be unexported now.
