Oh what a nightmare you got into there.
Curious that ACPI has SPI CS as always active high,
but that just underscore that we *really* need to
abstract this out to avoid really complex specialcasing.
Interesting that the PXA2xx XScale lives in Merrifield,
I didn't know. Reminds med of how the Samsung
hardware is alive and well in the recent Apple M1 laptops.
Yours,
Linus Walleij
