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