[U-Boot] alias in powerpc device tree

It appears that u-boot expects an alias list in the device tree. I only found this in the code for the fdt processing.

I'm working on getting our device tree correct to be able to allow u-boot to alter the device tree.

Is this all that's needed as my device tree is good as far as the kernel booting with it and u-boot passes it fine to the kernel such that it boots?

Or somewhere there's some documentation that I didn't read and should have?

Thanks, John
