OK, I will leave uart0 untouched, that's a good point.

OK, sounds reasonable, but also a bit contradictive. One the one hand 
you prefer consistency (so, let uart2-3 follow uart1 and include rts/cts 
in them), on the other hand the common case over the rare (so split off 
rts/cts). What should I do with uarts2-3 and should I do that to uart1 
too?

Moreover, Chen-Yu prefers to drop _a and @0 when they are redundant, 
which does not appear to be the convention, looking at existing 
sun*dsti. What's your opinion on this?

Best,
Jorik
