+Add support for:
+ GD5F{1,2}GM7{U,R}ExxG
+ GD5F4GM8{U,R}ExxG
+
+These are new 27nm counterparts for the GD5FxGQ4 chips from GigaDevice
+with 8b/512b on-die ECC capability.
+These chips (and currently supported GD5FxGQ5 chips) have QIO DTR
+instruction for reading page cache. It isn't added in this patch because
+I don't have a DTR spi controller for testing.
