- Drop a now obsolete ppc4xx_edac driver
- Fix conversion to physical memory addresses on Intel's Elkhart Lake and Ice
Lake hardware when the system address is above the (Top-Of-Memory) TOM
address
- Pay attention to the memory hole on Zynq UltraScale+ MPSoC DDR controllers
when injecting errors for testing purposes
- Add support for translating normalized error addresses reported by an AMD
memory controller into system physical addresses using an UEFI mechanism
called platform runtime mechanism (PRM).
- The usual cleanups and fixes
