[U-Boot] [PATCH 03/10] AVR32: Make cacheflush cpu-dependent

Fri Oct 10 15:15:45 CEST 2008
The AT32UC3A series of processors doesn't contain any cache, and issuing
cache control instructions on those will cause an exception. This commit
makes cacheflush.h arch-dependent in preparation for the AT32UC3A-support.
