Add data cache support for ARM V7 systems. Used cache flush
functions from linux:arch/arm/mm/cache-v7.S developed from
Catalin Marinas.
Enable "cache" command on Beagle board and test performance.
Test 1: Loading 127 MB of data from NAND flash into RAM:
Instr. Cache off on on
Data Cache off off on
--------------------------------------------------
Beagle (Cortex A8) 116s 106s 30.3s = x 3.8
Test 2: uncompressing a gzipped image from RAM to RAM
(size compressed: 6.5 MiB, uncompressed: 35 MiB):
Instr. Cache off on on
Data Cache off off on
--------------------------------------------------
Beagle (Cortex A8) 1.84s 1.64s 0.12s = x 15.3
