OF is indeed an abbreviation for Open Firmware...
Originally, the of_*() code was written to interact with device trees
provided by Open Firmware.  Later, it was extended to work with
flattened device trees (FDT) provided by something other than Open
Firmware.

... but no real Open Firmware is involved on Renesas ARM platforms,
so DT is more appropriate here.
