Subject[PATCH v4 0/5] mtd: Qualcomm NAND controller driver
Date
Add support for the NAND controller driver for SoC's that contain EBI2.
For now, the only SoC upstream that has EBI2 is IPQ806x.

The original version was posted a while back. The main comments were
about the driver not being able to use nand_bbt. This was because the
controller could read factory bad block markers only in RAW mode. This
forced us to implement our own versions of chip->block_bad and
chip->blobk_markbad, and also we had to skip creating a BBT.

Discussions with Kevin Cernekee concluded that having a new BBT flag
that incorporates this controller's special requirement is a possible
option.

The new version makes use of this flag and now uses nand_bbt, at the
cost of implement read_oob_raw and write_oob_raw ops.

The patchset requires the v6 ADM dmaengine patches posted by Andy:

v4:
- Some more fixes. Mentioned in patch's changelog.

v3:
- Various fixes and clean ups suggested by Stephen Boyd.

v2:
- Added a new BBT flag that allows us to read BBM in raw mode
- reduce memcpy-s in the driver
- some refactor and clean ups because of above changes

v1:
- original series:
