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.
