[U-Boot-Users] Linux with U-Boot

[Ganesh Ramachandran]

I am using U-Boot loader 1.1.4 and I am using IntegratorCP ARM Boards.
I am facing the problems while booting, I debugged my Kernel with Low
Level Debugging.I think My problem is in 'Call_Kernel' Function in
head.S and I am using kernel 2.6.16.

## Checking Image at 00007fc0 ...
