[PATCH v3 0/8] New Arasan NAND controller driver

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

New Arasan NAND controller driver

Hello,

This is a deep rework of Naga's Arasan NAND controller driver. This
version is the final version and works with software ECC. It relies on
a previous series called "Supporting restricted NAND controllers" that
brings more flexibility to the NAND with the goal to support
restricted controllers like this one.

Cheers,
Miquèl

Changes in v3:
* Prefix specific clock definitions with XLNX as they do not apply for
  any other SoC and are attached to a single compatible.
* Used field getters/setters as defined in bitfield.h.
* Force casting to u32 before shifting u8 values by 8 16 or 24 bits.
* Comply with the recent core changes and select manually
  nand_monolithic_read/write_page_raw() helpers.
* Add MAINTAINER patch.
* Add a bit extraction helper in the core.
* Rename BCH functions.
* Add a swapping bit mechanism to BCH.
* Support the hardware ECC engine.

Changes in v2:
* Working ->exec_op() implementation relying on core changes.
* Dropped the ECC support for now, will be part of another series if
  this patch is accepted.
