Hello,

JEDEC STANDARD JESD216 for Serial Flash Discovery Parameters (SFDP)
provides a mean to describe the features of a serial flash device
using a set of internal parameter tables. Support in Linux has been
added some time ago and the spi-nor driver is using it more often
to detect the flash settings and even flash models.

This is the initial framework for the RDSFDP command giving access to
a private SFDP area under the flash and one example for the n25q256a
to check this is a good approach.

Thanks,

C.
