MIPS: Cavium: Add EDAC support.
Drivers for EDAC on Cavium. Supported subsystems are: o CPU primary caches. These are parity protected only, so only error reporting. o Second level cache - ECC protected, provides SECDED. o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will will only initialize if ECC is enabled on a system so is safe to run on non-ECC memory. o PCI: Parity error reporting Since it is very hard to test this sort of code the implementation is very conservative and uses polling where possible for now.
