OK. Do you have a kernel config file we can commit to the tree? I don't
even know if it compiles, apart from your dmesg posts. I wasn't sure based
on your email, so I thought I'd ask for clarification.

CNS1102 is 922T which is armv4. I couldn't even find an eval board to try
to boot it on, nor any board with more than 16MB on the consumer gear that
it's in on ebay. And it's always a pain to get stuff on gear of that era
unless you get lucky...

The number of users on armv5t is declining. We're not removing it for 12
(since there's several known users), but will have a discussion about that
after we branch 12 whether or not we'll keep it for 13. Since there are
users, we need to understand the impact of keeping the port or retiring it
on them. Unlike these early parts where there's no known users...
