If we call flush_cache(0xfffff000, 0x1000) it would never
terminate the loop since end = 0xffffffff and we'd roll over
our counter from 0xfffffe0 to 0 (assuming a 32-byte cache line)

lib_ppc: rework the flush_cache 2008-12-15T21:31:39+00:00 Dave Liu daveliu@freescale.com 2008-12-05T07:36:14+00:00 e39cd81c44740d7355d277ed3d38536cbe1e003d - It is possible to miss flush/invalidate the last cache line, we fix it at here. - add the volatile and memory clobber. They are pointed by Scott Wood. Signed-off-by: Dave Liu <daveliu@freescale.com>

ppc flush_cache: add watch-dog triggering into the loops. 2008-04-29T12:48:50+00:00 Yuri Tikhonov yur@emcraft.com 2008-04-29T11:32:45+00:00 138105efe1d2b1a40a3a97b4c1f85c2111bea2d8 Some boards (e.g. lwmon5) need rather a frequent watch-dog kicking. Since the time it takes for the flush_cache() function to complete its job depends on the size of data being flushed, one may encounter watch-dog resets on such boards when, for example, download big files over ethernet.
