Subject: ppc4xx: Add dcache_enable() for 440
X-Git-Tag: v1.3.3-rc1~41^2~10
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=8deafdc6ad368368cf03b58cab4bd39f45d64b5c;p=u-boot

ppc4xx: Add dcache_enable() for 440

dcache_enable() was missing for 440 and the patch
017e9b7925f74878d0e9475388cca9bda5ef9482 ["allow ports to override bootelf
"] behavior uses this function.

Note: Currently the cache handling functions like
d/icache_disable/enable() are NOP's on 440. This may be changed in the
future.
