Subject: [PATCH v2 0/7] mtd: nand: Abstract away the NAND interface type
Hi,
This series is aiming at providing a generic NAND layer to share code
between different NAND based devices.
We currently have 3 different interfaces to interact with NANDs:
- Raw NANDs
- OneNANDs
- SPI NANDs
Apart from the way these NAND devices are accessed they have a lot
in common, like the way the memory is organized, or their constraints.
This is usually a good sign that some work should be done to factorize
the code.
This work has been started by Peter who wanted to re-use the BBT
code for its SPI-NAND driver. But I think we can push it further
other stuff (the software ECC implementation, or the way offsets are
converted to block/page number).
Peter, can you please review/test this version, and if possible, post
the code you've done to support SPI NANDs.
Thanks,
Boris
Changes since v1:
- use the 'raw' prefix instead of 'rawnand'
- fix a few coding style issues and typos
Boris Brezillon (7):
mtd: nand: Rename nand.h into rawnand.h
mtd: nand: move raw NAND related code to the raw/ subdir
mtd: nand: add a nand.h file to expose basic NAND stuff
mtd: nand: raw: prefix conflicting names with nandc instead of nand
mtd: nand: raw: create struct rawnand_device
mtd: nand: raw: make BBT code more generic
mtd: nand: move BBT code to drivers/mtd/nand/
