* ppc4xx: Add dcache_enable() for 440Stefan Roese2008-04-22-0/+2
| | | | | | | | | | | | 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. Signed-off-by: Stefan Roese <sr@denx.de>
