This patch adds support for ECC error decoding for F15h M60h processor. Aside from the usual changes, the patch adds support for some new features in the processor: - DDR4(unbuffered, registered); LRDIMM DDR3 support - relevant debug messages have been modified/added to report these memory types - new dbam_to_cs mappers - if (F15h M60h && LRDIMM); we need a 'multiplier' value to find cs_size. This multiplier value is obtained from the per-dimm DCSM register. So, change the interface to accept a 'cs_mask_nr' value to facilitate this calculation - switch-casing determine_memory_type() - done to cleanse the function of too many if-else statements and improve readability - This is now called early in read_mc_regs() to cache dram_type Misc cleanup: - amd64_pci_table[] is condensed by using PCI_VDEVICE macro. Testing details: Tested the patch by injecting 'ECC' type errors using mce_amd_inj and error decoding works fine.
