How would you boot that cdrom on real hardware?  Does U-Boot support booting 
from a cdrom?
I am using the bootable CDROM option only because qemu requires the CDROM/hard 
disk images to be bootable. On real hardware, we use the bootm option of 
U-boot. Using qemu, I was not able to find helpful instructions to boot 
netbsd/ppc via. uboot (as bootloader). The nearest that I could come to booting 
netbsd/ppc combination was through ofwboot as the bootloader.
I am now trying to use the -kernel option to boot the netbsd kernel. Looks like 
the -M mpc8544ds option mandatorily requires a FDT. The netbsd that we are 
using does not have the FDT option when it is compiled. So trying to understand 
more about FDT and the qemu implementation of FDT, to debug the booting issue.
