/**
|

* GD (GigaDevice) SPI flash chip_drv, uses all the above functions for its operations. In
|
|
* default autodetection, this is used as a catchall if a more specific chip_drv
|
|
* is not found.
|
|
*
|
|
* Note that this is for GD chips with product ID 40H (GD25Q) and 60H (GD25LQ). The chip diver uses
|
|
* different commands to write the SR2 register according to the chip ID. For GD25Q40 - GD25Q16
|
|
* chips, and GD25LQ chips, WRSR (01H) command is used; while WRSR2 (31H) is used for GD25Q32 -
|
|
* GD25Q127 chips.
