Thanks Ian. I'll adjust. The dtb files don't hurt anything, and it would be
extra config to have
some platforms do it and not others (something I'm trying to avoid). I'll
document it for later.
However, if there's no point to the uenv file, that's easy to just remove.

Of all the arm platforms we support, only RPi and RPi2 require the dtb
files to be in the fat partition.

The only advantage to an empty uEnv.txt file is that it will suppress a
warning about not being able to read it.  There's no way to suppress a
similar warning about a bad saved-environment checksum that u-boot
emits if you've never changed anything and done a saveenv.
