I have a W25Q16BVSSIG chip which I can read and write successfully with flashrom. However, the chip is not natively supported.

Attached is the output of the flashrom command.

Let me know if there is anything I could help with to have this one added to the list of natively supported chips.

W25Q16BVSSIG

Vendor: Winbond

Device Size [kB]: 2048 

Type: SPI

Voltage [V]: 2.7 to 3.6
