I wasn't sure based on your email, so I thought I'd ask for clarification. This is kernel configure file. https://svnweb.freebsd.org/base/head/sys/arm/conf/RT1310?view=markup dmesg have pci log but not commit yet. Thanks Hiroki Mori > > >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.

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.
