Hi Scott et al,

I seem to get further with the cuboot-824x file- with the cuboot-pq2 file the 
boot sequence doesn't even reach the 'zImage starting' stage. The machine 
reboots just before it should be printing out 'zImage starting'. 

Is there a way I can get more detailed debug to see what's happening?

Do settings from bd_info struct override the settings from the DTS file?

Also, a lot of the settings passed from u-boot in our 2.6.14 environment are 
plain wrong eg. wrong memory, wrong processor speed. In this case, the correct 
settings are set elsewhere (for memory, it is a kernel parameter ie. mem=32M, 
and the processor speed is set in the 2.6.14 'make menuconfig'). Therefore, 
the machine still boots into Linux correctly. For 2.6.27, would these 
incorrect settings be causing my problems?
