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

methods
mtd: nand: gpmi: add gpmi_move_bits function
mtd: nand: gpmi: add proper raw access support
mtd: nand: gpmi: add raw oob access functions
