[PATCH v4 0/4] 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.

I also updated the nand_ecc_ctrl struct documentation to clearly state that
specific layouts should be hidden when accessing the NAND chip in raw mode.

Best Regards,

Boris

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
