Yes, thanks for pointing that out. I moved it to 0xFC0000 (about 16MB).
This time it seems uncompressed ok but it hung forever after that. Any
suggestions how to debug this? How do I turn on the kernel debug messages
from the config menu?
=> bootm 0xfc0000
## Booting image at 00fc0000 ...
Image Name: Linux-3.7.8
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 2571933 Bytes = 2.5 MB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
