Merge tag 'edac_updates_for_v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras

Pull EDAC updates from Borislav Petkov:

 - 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
