With this patch the L2 cache is enabled on Canyonlands to increase the overall performance. There is a known cache coherency issue with the L2 cache, but this is related to the high bandwidth (HB) PLB segment where the memory address is 0x8.xxxx.xxxx (low bandwidth PLB segment is mapped to 0x0.xxxx.xxxx). Since this HB address is currently unused it is safe to enable the L2 cache. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
