Log message:
Code for the external L2 cache controller on Indy/Indigo2 R4600SC and Indy
R5000SC processor modules; these sport an up to 512KB, physically indexed,
write-through L2 cache which is not connected to the canonical external cache
interface of these processors (hence requiring specific code to drive it).
The cache is enabled early and disabled before returning to ARCBios (for very
nasty things happen otherwise).
Tested on R5000SC, will be tested on R4600SC soon.
