Hi Scott,
How do I find the address, reg, and range for nodes like localbus,
soc, eth0, cpm, serial etc.?
If your CCSRBAR is 0xfa200000, then pretty much anywhere you see
0xff0xxxxx change it to 0xfa2xxxxx.
I managed to proceed a little bit further.

The kernel doesn't seem to start. What could go wrong here?
Pretty much anything. :-)
Make sure that you've got Linux platform code enabled that matches the
top-level compatible of your device tree. Try enabling
PPC_EARLY_DEBUG_CPM, making sure to update PPC_EARLY_DEBUG_CPM_ADDR to
0xfa202008.
