Needs updating to remove the bamboo references. In fact we can
probably get rid of this "To build" comment that's been copied to just
about every dts ever.

The first compatible entry should always be the precise model, so in
this case "ibm,uic-440epx". If it is (supposed to be) identical to
the UIC in the 440GP, it can also have an "ibm,uic-440gp" entry, but
since I believe all the UICs are supposed to operate the same, I think
that's implicit in the "ibm,uic" entry.
This goes for all the entries below where you list "ibm,....-440gp" or
or "ibm,....-440ep" or "ibm,.....-440spe" first instead of
"ibm,....-440epx".

Should have a precise -440epx compatible, as well as the more general one.

Comment is for Bamboo and does not match the ranges property below.

This flash binding needs to be replaced, but I guess that's not really
your problem.

"ibm,emac-axon" is definitely wrong, since this isn't an Axon chip.
