Please keep picochip,pc3x2-rtc in the compatible list otherwise we won't
boot any more.

The same here. Also, I'm not sure that the split of these patches is
correct - there isn't any bisectability here as you remove the timer in
this patch but picoxcell won't build. I think squashing these 2 patches
is fine.
I can't test on hardware right now, but with those changes:
