Rui Sousa	4f6627ac3b	[ARM] 4568/1: fix l2x0 cache invalidate handling of unaligned addresses ... The l2x0_inv_range() function doesn't handle unaligned addresses correctly. It's necessary to clean the cache lines that are at the start and end of the invalidate range, if the addresses are not aligned, to prevent corruption of other data sharing the same cache line.

Catalin Marinas	0762097625	[ARM] 4500/1: Add locking around the background L2x0 cache operations ... The background operations of the L2x0 cache controllers are aborted if another operation is issued on the same or different core. This patch protects the maintenance operation issuing/polling with a spinlock.

Catalin Marinas	382266ad5a	[ARM] 4135/1: Add support for the L210/L220 cache controllers ... This patch adds the support for the L210/L220 (outer) cache controller. The cache range operations are done by index/way since L2 cache controller only accepts physical addresses.
