I wanted to try this patchset, so I picked [1], since I didn't feel like fishing
out patches from the list. Especially since this wasn't sent as a series, but as
separate patches, which makes things annoying.
The [1] does not even compile, which is surprising. I would expect that if you
submit patches, you would at least compile-test them. Sigh. I needed this patch:

Once I managed to fix things, I compiled ap121. I tried booting it on arduino
yun (ar9331), but it hung in start.S in setup_c0_status . If I comment this
out, it hangs in lowlevel_init, right at the beginning. That's where I gave up.
