That would leave only Sun4m in the 32bit kernel, which still works and
has plenty of ongoing user interest.
Chris don't over-exaggerate the state.
The truth is that the whole sparc32 port is in a state of mild
disrepair, and many of the issues apply to all the port rather than
just one family of systems. I think someone suitably motivated
could get most of the bugs sorted out.
There is no reason to drop support for SS1 machines, we already fully
build the software device tree and use all of the generic OF
infrastructure in the Linux kernel on those systems. It is not a road
block at all for the OF genericization work, if that's what you read
into wmb's email.
Your call, as you say there is little to be gained other than tidyness.
FWIW my opinions (and ICBW) are based on :-
Sun4c machines have a max of 48 or 64Mb and very few are still working
Sun4d has never had SMP support and this is apparantly problematic
due to Cray interlectual property causing a lack of bus documentation.
Running these heavy and power hungry lumps UP is a bit silly.
