I have pulled it into the next/cleanup2 branch now, sorry for the
delay. Unfortunately I noticed one more thing I didn't like and
did not pull the final patch of the branch, but only the other patches.

The problem I noticed is the soc-bus support: I noticed that you
are populating the entire device tree under the soc node, including
any top-level devices, and that the "xlnx,zynq-devcfg-1.00.a"
node is part of that.

I think what you should try instead is to have only the
amba bus and its children as part of the soc-bus, but other
top-level devices (e.g. board clocks) outside of the soc
node. Also, it would make sense to merge the devcfg stuff
with the amba node, since it's really what makes up the
soc. Does that make sense to you, or do you have reason to
believe it won't work?
