2019-05-05dm: cache: add the pl310 cache controller driverDinh Nguyen
Add a PL310 cache controller driver that is usually found on ARMv7(32-bit) devices. The driver configures the cache settings that can be found in the device tree files. This initial revision only configures basic settings(data & instruction prefetch, shared-override, data & tag latency). I believe these are the settings that affect performance the most. Comprehensive settings can be done by the OS. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
