    Subject[PATCH 00/16] mtd: nand: sunxi: various improvements/fixes
    Date
    Hi,

    This patchset aims at fixing a few minor bugs, and improving performances
    of NAND accesses going through the sunxi NAND controller.

    Note that patch 5 exports functions provided by the core which are needed
    in patch 6 to still support raw OOB accesses. Other patches are just
    fixes or improvements only touching the sunxi driver itself.

    Here are the main improvements:
    - queue CLE/ALE requests instead of forcing the controller to issue each
    cmd and address cycle separately
    - benefit from ECC correction on protected OOB bytes
    - use polling instead of interrupt-based waiting (avoid scheduling
    overhead for short wait period)

    I'm preparing another series based on this one to add page operations
    and DMA support, which, according to my first tests will bring a huge
    speed improvement (at least x2 on read accesses, and even more when
    ONFI timing mode > 0 is used).

    Stay tuned.

    Best Regards,

    Boris
