Thanks for the patches. I've tested a few drivers and compile tested as
much as I can, and everything looks good. Patches 5 and 59 (m25p80.c and
fsl-quadspi.c) didn't apply cleanly yet, as those drivers have had some
concurrent changes, so I didn't take them yet. If it's trivial to fix
up, I'll apply themself. Stay tuned.

Regards,
Brian
