Subject: [PATCH 5/5] mtd: spinand: gigadevice: add support for GD5FxGM7xExxG
|
||
|
|
|
||
|
|
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.
