I'm not convinced it is worth the hassle to merge in the 710... if it was
possible in a straightforward way, we'd done it when writing the '770
('720,'770,and '8xx look all very similar; the only differences being
capabilities implemented (like wide scsi, maximum sync speed,
availability of on-chip script ram; and of course 8xx are PCI).
The '710 (and '700) chip looks similar to the later ones, and uses the same
script processing language, but does not have some registers, and has some
others in a different place. Among them is the _chip version field_, which
tells you (for the later ones) the capabilities available (max. speed, etc.).
What definitely should be done is to bus_dmaify the 710 driver and use a common
one between Amiga and VME machines (I think). I only need a volunteer to do
