How do I support different flash chips?

The code to support flash chips is in pmon/lib/nvram.c.
This code will try to identify those flash chips that
follow the CFI (Common Flash Memory Interface) standard 
with the Vendor Command Set & control Interface ID Code 2
(the AMD/Fujitsu Standard Command Set).

If one has a flash chip that follows a different standard,
one will need to modify pmon/lib/nvram.c.

If one has a flash chip that mostly follows the above standard,
one will need to examine, and if necessary, modify pmon/lib/nvram.c.

Flash is accessed through the ELB (External Local Bus).  One may
need to change the chip select starting address or size for accessing
flash.  Please see the file pmon/FAQs/FlashStartAddresses.
