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 v4: * Collected Reviewed-by tags. * Dropped Ivan from the list (did not find his contact). * Wrapped commit log. * Fixed typos in the commit logs/comments. * Took authorship of all patches. * Added more details on the BCH changes. * Documented the new bch_control entry. * Made the swap bit calls conditionals in bch_encode to avoid penalizing people that do not use it. * Patched bch_init() to take an extra argument. * Dropped calls to nand_release(), use the construction proposed by Boris instead. * Dropped a useless NFC struct field. * Added a comment on not having an interrupt for RB. * Checked the number of steps requested is compatible with the controller limitations. * Reworked anfc_exec_op as suggested to treat the check_only argument another way. * Change the comment stating that the controller has only one CS. * Clarified the interrupts signals vs. interrupt status bits. 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.
