I am using Diskonchip millennium with boot capability. I just want to know if diskonchip is mapped to the high order physical address (at reset) and is any remapping is done later?

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!
