[coreboot] ### LX800 , NAND FLASH, Booting

We are using coreboot on an LX800+CS5536 custom platform.
Coreboot + FILO is loaded into a standard flash prom on the LPC bus
It boots up and then accesses a 1GB compact flash which stores Linux 2.6 and
our applications.

I am really interested in pulling that bulky, expensive compact flash and
connector from the design.

What are the options for using a NAND flash to replace the Compact Flash?
Would we need to use a Linux-As-Payload setup and then just map the NAND as
a YAFFS/JFFS device in linux? What about initial loading of the filesystems
on the NAND? Would we boot up with NFS on linux the first time, then pull
down a filesystem image into the NAND flash once booted on NFS?

I'm interested to hear ideas on how to do this or if no one has done it yet.
