That is a rather odd address to have an abort at assuming you're using
the uImage obtained from `make uImage` because there are normally NOPs
from 0x8000 through 0x801f, e.g.

../BUILD/integrator/default/arch/arm/boot/compressed/vmlinux:     file format elf32-littlearm

Disassembly of section .text:

FWIW, I just booted 2.6.10-rc3 bk latest on IntegratorAP with ARM920T
processor module using latest u-boot CVS:


Integrator-AP # bootm 0x800000
## Booting image at 00800000 ...
   Image Name:   Linux-2.6.10-rc3

OK
No initrd
