I am working with a powerpc embedded system where u-boot seems to be passing in 
a constructed fdt (or one embedded in u-boot) as opposed to one that is either 
passed directly to bootm or as the third image of a multi-file image.

I'm sure sure that the system is NOT using my dtb file because I modified the 
my linux platform file to print out the "model" and "compatible" properties of 
root, and they make sense, but are not the values that I pass in with my dtb.

I've tried "bootm ${kerneladdr} - ${dtbaddr}" for nfs boot, and I've 
constructed a multi-file uImage with kernel:initramfs:dtb.  The behavior is the 
same in all cases.  Is this expected behavior, and if so, is there some way to 
force u-boot to use my dtb file?

Thanks,

JR
