I'll NAK this one because:
1) obviously the big #ifndef CONFIG_SYS_DCACHE_OFF / #else /#endif is there to provide either working D$ functions or empty ones;
2) enable_caches() exists only in the "then" branch, not at all in the "else" branch, which makes it a surprising exception;
3) enable_caches() is the only function in the if/then/else acting on I$ as well as D$;
... so I suspect it did not actually belong in the big if/then/else in the first place and should not be modified but moved after the #endif.
Please provide a V2 patch, I promise it'll get processed faster than this V1.
Amicalement,
