Then what do you suggest? I can think of a few alternatives.

Leave the current name and make the hidden option a new name like
ARCH_xx_OPTIONS. This would require renaming ARCH_xxx for each platform
all over the tree. I don't care to sign up for that task...

Well, requiring everyone to spend hours redoing their configuration also
isn't practical either.

Move platforms one by one out of the choice as they are converted. I
can't think of a reason for a platform to be in both places except we
would have to figure out something for getting DEBUG_LL to work.

No you don't.  We've already decided how we're going to deal with
DEBUG_LL, and we are _not_ going to make that multi-platform.  You
select one of the output options, and that is it.  We've already
been moving in that direction, albiet slowly.  Again, anyone who wants
to be part of a multiplatform kernel better use the provided choice
or they will get no DEBUG_LL facility - simples.

That also means we can start to think about moving the mach/debug-macros.S
header elsewhere, remembering that this facility is shared between the
decompressor for debugging and the kernel.

Remember that DEBUG_LL is the low-level *debug* facility.  It is not
the early console, even if it ended up being used as such (which is
not something I really care for.)  Read the previous discussions on
this subject if you disagree, but I'm not changing my position over
DEBUG_LL because that will just require me to re-invent the facility
yet again (which is what DEBUG_LL is there to stop.)  It was _never_
intended to be an early console facility.
