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.

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.

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.
