A mx25l25635f chip model is generally found on these machines. It's
newer and uses 4B opcodes which is better to exercise the support in
the Linux kernel.

The witherspoon I checked also reported mx25l25635e in dmesg for the
FMC.

You do say "generally" in the commit message though.

You can not tell from dmesg.

The MX25L25635F and MX25L25635E models share the same JEDEC ID and
the spi-nor flash device table only contains a mx25l25635e entry.
The MX25L25635F is detected in mx25l25635_post_bfpt_fixups using SFDP.

That's why I added this warning  :
