Hello,
I'm trying to load Linux from U-Boot. I am using ELDK 4.2 with U-Boot
2009.03 on an EP88xC rev1.1 board (MPC885 cpu, 64MB RAM, 32MB FLASH).
The linux kernel sources were obtained from instructions at
"http://www.denx.de/wiki/view/DULG/LinuxConfiguration#Section_6.1.";
and the FDT blob (dtb) was generated from
"linux-2.6-denx/arch/powerpc/boot/dts/ep88xc.dts". Below is my output
from boot to hang:

I did a post-mortem analysis
(http://www.denx.de/wiki/view/DULG/LinuxPostMortemAnalysis) and came
up with the following message:

I'm not quite sure where to go from here to get linux working. Anybody
have any suggestions?
Thank you,
Mikhail Zaturenskiy
