   4 Subject: [PATCH 4/5] mtd: spinand: gigadevice: add support for GD5F{2,
   5  4}GQ5xExxG
   6
   7 Add support for:
   8  GD5F2GQ5{U,R}ExxG
   9  GD5F4GQ6{U,R}ExxG
  10
  11 These chips uses 4 dummy bytes for quad io and 2 dummy bytes for dual io.
  12 Besides that and memory layout, they are identical to their 1G variant.
