Hi Linus,

The following changes since commit b28a960c42fcd9cfc987441fa6d1c1a471f0f9ed:

  Linux 3.14-rc2 (2014-02-09 18:15:47 -0800)

  mtd: nand: omap: fix ecclayout->oobfree->length (2014-02-23 14:49:57 -0800)

----------------------------------------------------------------
Two main MTD fixes:

 1. Read retry counting was off by one, so if we had a true ECC error (i.e., no
    retry voltage threshold would give a clean read), we would end up returning
    -EINVAL on the Nth mode instead of -EBADMSG after then (N-1)th mode

 2. The OMAP NAND driver had some of its ECC layouts wrong when introduced in
    3.13, causing incompatibilities between the bootloader on-flash layout and
    the layout expected in Linux. The expected layouts are now documented in
    the commit messages, and we plan to add this under Documentation/mtd/nand/
    eventually.
