<div class='commit-subject'>Merge tag 'nand/for-4.7' of github.com:linux-nand/linux</div><div class='commit-msg'>Updates from Boris Brezillon:

This pull request contains the following infrastructure changes:
* introduction of the ECC algo concept to extend the ECC mode one
* replacement of the nand_ecclayout infrastructure by something more
  future-proof.
* addition of an mtd-activity led trigger to replace the nand-activity
  one

And a bunch of specific NAND driver improvements/fixes. Here are the
changes that are worth mentioning:
* rework of the OMAP GPMC and NAND drivers
* prepare the sunxi NAND driver to receive DMA support
* handle bitflips in erased pages on GPMI revisions that do not support
  this in hardware.
