[PATCH v6 0/3] mtd: nand: gpmi: add proper raw access support

[Boris Brezillon]

Hello,

This series provides an implementation for raw accesses taking care of
hidding the specific layout used by the GPMI controller.

Best Regards,

Boris

Changes since v5:
 - rename gpmi_move_bits into gpmi_copy_bits

Changes since v4:
 - fixed a few corner cases in gpmi_move_bits (tested it with:
   https://github.com/bbrezillon/gpmi-move-bits-test/blob/master/gpmi-move-bits-test.c)
 - add documentation and comments for the new gpmi functions

Changes since v3:
 - add comments to the gpmi_move_bits function
 - extend raw read/write documentation
 - move last part of the raw_page_read function into a conditional block

Changes since v2:
 - fixed a bug in gpmi_move_bits
 - add a raw_buffer field to be used when using raw access methods
   (experienced memory corruptions when directly using page_buffer_virt
   buffer)
 - add raw OOB access functions
