   4 Subject: [PATCH 5/5] mtd: spinand: gigadevice: add support for GD5FxGM7xExxG
   5
   6 Add support for:
   7  GD5F{1,2}GM7{U,R}ExxG
   8  GD5F4GM8{U,R}ExxG
   9
  10 These are new 27nm counterparts for the GD5FxGQ4 chips from GigaDevice
  11 with 8b/512b on-die ECC capability.
  12 These chips (and currently supported GD5FxGQ5 chips) have QIO DTR
  13 instruction for reading page cache. It isn't added in this patch because
  14 I don't have a DTR spi controller for testing.
