[PATCH 0/2] New Arasan NAND controller driver

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

Hello,

This is a deep rework of Naga's Arasan NAND controller driver.
This version is preliminary, allows to boot, but there are two
remaining changes that must be written:
1/ the core must be adapted to force "packed" operations instead of
   using a splited scheme (this will need the NAND bounce buffer handling
   to be reworked as well)
2/ a deeper understanding of the hardware ECC engine's behavior in
   order to workaround its limitations.

The drive probes, registers an MTD device and then NAND chip(s) can be
initialized. Regular read/write operations need more work for now.

The bindings have been changed a little bit and the file translated
into json schema.

Cheers,
Miquèl
