Oh nom nom nom. Your CPU has not been ported to loading microcode from CBFS.

We're a bunch of old wizard farts using grep blackmagic.

config CPU_MICROCODE_IN_CBFS
        default CPU_MICROCODE_CBFS_GENERATE if CPU_MICROCODE_IN_CBFS
        default CPU_MICROCODE_CBFS_NONE if !CPU_MICROCODE_IN_CBFS

The rest is left as an excercise to the reader.
