Can you explain what a "NAND boot system" is?

When I boot an AT91SAM9xxx from NAND, I tell buildroot to build
a JFFS2 root image, a uImage kernel with MTD/JFFS2 support, put
the resulting kernel and root image into NAND, and configure U-Boot
to boot from NAND.

Presumably because nobody has bothered to submit one.

I'm still not sure what you're after beyond selecting JFFS2 for
the root fs type and enabling MTD and JFFS2 support in the
kernel.  Can you explain what it is you're missing?
