transfer ends in stead of doing it before starting a new transfer.
Use a different CSR bit to wait for "chip not busy" (may be necessary to

to match `sd' devices against the PROM's boot path.

from/to raw partitions), by using the "Transfer Pad" command when the
transfer count reaches zero.
Support for multiple register banks on SBUS devices (based on patches
from Francis Dupont).
Highlights:
romaux defines an array of register spaces.
pay attention to `vactype'.
quirks handling 4/100 idiosyncracies.
