Linuxbios with Diskonchip?

[gizara]

If I remember correctly, Disk-on-Chip comprises NAND flash technology which
inherently cannot execute in place, strictly sequential (data) accesses...
So you would still need some sort of rudimentary boot flash(NOR) or other
ROM to execute code to first load the BIOS, then the kernal, into shadow,
then main (DRAM) memory locations, respectively.

In a system I'm architecting we're still going to use a 256Kx8 flash for
LinuxBIOS, from there use JFFS2 and associated utilities to get the kernal
and various applications and data from a bare NAND on board.

This link and its links go into much more detail than I can in this email
about issues you may face:

Good Luck!
