v7_flush_dcache_all, because it depends on omap ROM code is not generic. Rename the function to 'invalidate_dcache' and move it to the omap cpu directory. Collect the other omap cache routines l2_cache_enable and l2_cache_disable with invalide_dcache into cache.S. This means removing the old cache.c file that contained l2_cache_enable and l2_cache_disable. The conversion from cache.c to cache.S was done most through disassembling the uboot binary. The only significant change was to change the comparision for the return of get_cpu_rev from cmp r0, #0 beq earlier_than_label Which was lost information to cmp r0, #CPU_3XX_ES20 blt earlier_than_label The paths through the enable routine were verified by adding an infinite loop and seeing the hang. Then removing the infinite loop and seeing it continue. The disable routine is similar enough that it was not tested with this method. Run tested by cold booting from nand on beagle and zoom1. Compile tested on MAKEALL arm. Signed-off-by: Tom Rix <Tom.Rix@windriver.com>
