Merge tag 'edac_for_4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp

Pull EDAC updates from Borislav Petkov:
 "A lot of movement in the EDAC tree this time around, coarse summary
  below:

   - Altera Arria10 enablement of NAND, DMA, USB, QSPI and SD-MMC FIFO
     buffers (Thor Thayer)

   - split the memory controller part out of mpc85xx and share it with a
     new Freescale ARM Layerscape driver (York Sun)

   - amd64_edac fixes (Yazen Ghannam)

   - misc cleanups, refactoring and fixes all over the place"
