For AT91SAM9 ARM 926 based chips, we can exceed the cache line length as we can access RAM even while in self-refresh mode. We keep plain access to CP15 for at91rm9200 as this feature is not available: instructions have to be in a single cache line. Signed-off-by: Nicolas Ferre --- Reading git-diff-tree failed
