I like to read what kind of platform the BMC is going into if you can
add that detail, but it's not essential.

Which driver supports this?
It would be great to see Facebook work to get the SPI NOR driver for
the ast2600 merged to mainline.
I doubt the IBM team will get to this, as we are using eMMC instead.

Have you verified that USB works with mainline? I've had reports of it
working on 5.8 but it seems to have regressed as of v5.10.

status = okay?
You should specify the pinmux too I think, even if the default happens
to work, so that other devices cannot claim the pins.
