2013-02-15ARC: Don't fiddle with non-existent cachesVineet Gupta
!CONFIG_ARC_HAS_(I|D)CACHE makes Linux disable caches (assuming they exist in hardware) - mostly for debugging issues with new peripherals. However, independent of CONFIG_ARC_HAS_(I|D)CACHE, Linux also needs to handle, non-existant caches, using the information in Cache BCRs (Build Configuration Reg) Reported-by: Alexey Brodkin <abrodkin@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2013-02-15ARC: Cache Flush ManagementVineet Gupta
* ARC700 has VIPT L1 Caches * Caches don't snoop and are not coherent * Given the PAGE_SIZE and Cache associativity, we don't support aliasing D$ configurations (yet), but do allow aliasing I$ configs Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
