I need some more help getting the multi-image to work.  I have the following files:

vmlinux.bin.gz (built myself)
rootfs.ext2.gz.uboot (from the BSP, because I don't know how to build a root 
file system.  I don't know what the ".uboot" is for.)
mpc8349emitx.dtb (built myself)

I create the multi image per you instructions, tftp them to $loadaddr (200000), 
and do "bootm $loadaddr".  I get this output:

bootm $loadaddr
## Booting image at 00200000 ...

So the image appears to be okay, but it doesn't boot at all.  Is there something 
obvious I'm doing wrong, or will I have to debug this?
