[Buildroot] Adding new processors and boards to buildroot

[Tim Barr]

How does something like this actually get done in buildroot? We have a
design based on the Atmel AT91SAM9G20 part, and the guy working with me
on software had to make a lot of modifications to the Timesys build in
order to support a different Ethernet MAC chip using the MII interface,
use the 32Mbit DataFlash, Use a 16 bit NAND Flash, boot from the NAND
Flash, and make some other I/O pin assignment different from the the EK
board. We are also using uboot 1.3.3 and had to modify it to work with
MII and a 16 bit NAND Flash. He is creating diff files so that other
people can setup the same compile code, how do you do something like
this in buildroot? I assume it has something to do with the config files
in the target directory.
 
And how do you set up buildroot to create a JFFS2 root filesystem for
the NAND Flash? Is it considered a parallel flash?? There is only an
option for DataFlash or parallel flash when I run menuconfig.
