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

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
