Subject: [RFC PATCH 0/2] mtd: nand: properly handle bitflips in erased pages

Hi Brian,

This is the patch series I promised a while ago.
The implementation should be generic enough to be used by controller
drivers.
The only problem I can see is for the GPMI controller which might produce
non byte aligned ECC data, and the nand_check_erased helpers are only
working with byte aligned buffers.

Best Regards,

Boris

Boris Brezillon (2):
  mtd: nand: add nand_check_erased helper functions
  mtd: nand: use nand_check_erased_ecc_chunk in default ECC read
    functions
