That's OK.

This should be investigated, though. I believe pretty much _all_ those
-O or -O2 lines are copy-paste anyway, nobody really ever thought about
which of them is appropriate for the resp. board.

Apart from possible romcc bugs I cannot think about a reason to not use
the -O2 option for all boards per default. Is there such a bug?
I can test -O vs. -O2 on some boards later, if needed.

(the -mcpu option is board-/cpu-dependent of course, and must stay
configurable)

This is also something we should look into later. I'd use the new
default for RAMBASE whereever possible, unless some boards have problems
with that (which we should find out).

I can do some tests on boards which used 0x4000 earlier.

Long-term this should move into a global file as it's pretty much
the same for all boards.

Global option, should probably not be per-board.

"2100 Server (SUN Fire v20z)" as per wiki (not sure if "Khepri" is the
official vendor name, if yes we should also adapt the wiki table).

Should be dropped, global options.
