As a quick guide:

Build the mtd support into the kernel.

If using modules, I'd suggest ordering them something like (depending on what 
support you've chosen of course)


Run the MAKEDEV script from the utils directory of the cvs tree to create the 
necessary files in /dev

Reboot. You should see a "Disk on Chip found at xxxxx" message followed by a 
"Giving out device <x> to DiskOnChip...". Generally I'd expect the DoC to be 

fdisk /dev/nftla and set up whatever partitions you want, then run mkfs to 
create the partitions. Mount and enjoy.

Alternatively you can create your own filesystems and dd them in directly.
