Hi all,

I faced an issue with a SPI flash on our board. We use a macronix
MX25L12835F [1]. Unfortunately this flash has the same JEDEC ID like
the MX25L12805D [2].

The newer MX25L12835F has support for dual/quad read mode and RDSFDP
while the older doesn't.

I thought that I could do a fixup with a device specific
post_bfpt_fixups() call but by now this seems not possible. The older
MX25L12805D has no flags set that allows a call to
spi_nor_sfdp_init_params() and implements the fixup.

Has anyone an idea how to solve this?
