known or probable to be compatible with this combination, what should I look for to attempt to assertain compatibilty? Does blob/mtd work transparently with a 16bit or 32bit ROM bus?

The MTD code ought to work with any CFI-compliant flash chip from Intel or
AMD, and with a few others too. In most combinations of bus size / interleave.I don't know about blob, but RedBoot should support most of the flash setups you're likely to encounter, too.
What about flashes that say they have CUI (Command user interface) and SR (Status register)?
what are CFI commands? are they 8bit, 16bit? if you have 2 chips giving you a 32bit databus, does it write out the same command on the high lane and the low lane?
I've noticed LART connects address and data lines to flash in positions most convienent to route. Does this break any CFI functionality?
