I started off doing that but had to split it up because how it handles
the nvram and bcm_tag to construct the partition layout is significantly
different. The nvram isn't even read from flash in bcm63xxpart, and the
psi size value isn't used by bcm963268.

With the device tree changes Brian's introducing it can be specified in
there, otherwise a common parser would need to read from the
miscStrapBus register which would be difficult for a partition parser as
it's not a device and has no memory resources.
