[Avila] RedBoot partition corrupted with bad image;

[Bhanu Prakash Adhikari]

My redboot partition got corrupted with my experiments to load custom
build redboot.

I copied the RedBoot image from Linux using /dev/mtd0. The bad part is
that the two boards I have, got RedBoot partition screwed.

1.	How can I make my board come alive?

2.	My board allows loading through http, tftp, and serial but not
from disk. I tried to load RedBoot using xmodem but got strange
characters. Ethernet was also not accessible as the NPE drivers were not
properly integrated with RedBoot. How can I successfully load the
redboot (ROM/RAM images) using serial, since I don't have JTAG?

4.	I tried to load SnapGear image on the board through xmodem so
that I can manipulate mtd0; but failed to load snapgear image.
