cache: Introduce external cache controller system support The cache API currently shipped in Zephyr is assuming that the cache controller is always on-core thus managed at the arch level. This is not always the case because many SoCs rely on external cache controllers as a peripheral external to the core (for example PL310 cache controller and the L2Cxxx family). In some cases you also want a single driver to control a whole set of cache controllers. Rework the cache code introducing support for external cache controllers.

cache: Add Aspeed AST10x0 external cache driver The CPU in Aspeed AST10x0 SOC is a ARM Cortex-M4 which doesn't internal cache memory. Aspeed implements an integrated system level cache to accelerate instruction and data memory accesses. Signed-off-by: Dylan Hung <dylan_hung@aspeedtech.com>
