[ARM] 3377/2: add support for intel xsc3 core
Patch from Lennert Buytenhek This patch adds support for the new XScale v3 core. This is an ARMv5 ISA core with the following additions: - L2 cache - I/O coherency support (on select chipsets) - Low-Locality Reference cache attributes (replaces mini-cache) - Supersections (v6 compatible) - 36-bit addressing (v6 compatible) - Single instruction cache line clean/invalidate - LRU cache replacement (vs round-robin) I attempted to merge the XSC3 support into proc-xscale.S, but XSC3 cores have separate errata and have to handle things like L2, so it is simpler to keep it separate. L2 cache support is currently a build option because the L2 enable bit must be set before we enable the MMU and there is no easy way to capture command line parameters at this point. There are still optimizations that can be done such as using LLR for copypage (in theory using the exisiting mini-cache code) but those can be addressed down the road.
