Bob, is there some upper bound we can use?  I'm happy to enlarge it
to whatever reasonable size is necessary.

The 'memory' node properties are the one thing I don't think we can
reasonably dynamically allocate memory for, so they have to be
statically sized.

With the changes we are discussing here, we are getting several
megabytes of BSS space back in the kernel image, so there is lots
of room for expanding the value of MAX_BANKS :-)

Also, that debugging message from read_obp_memory() should also
print out "ents" so we know how much we might need to expand it
in the future.
