The SiFive boards have

oneOf:
- items:
- enum:
- sifive,hifive-unleashed-a00
- const: sifive,fu540-c000
- const: sifive,fu540

IIUC there's no practical difference between a single-option enum and
the const, but it does bring up the board version number. Is there any
revision number on the beaglev boards?
