Shouldn't this be 0x800000000 with ~0x80000000 length (or whatever is
more common)? Or did I miss some ranges?

The base model has 8GB of RAM, and RAM always starts at 0x800000000, 
hence that reg property.

It's not actually useful to try to boot Linux like this, because it'll 
step all over device carveouts on both ends and break, but since those 
are potentially dynamic it doesn't really make sense to use a more 
specific example for the dts.

E.g. on my system, with my current firmware version, this ends up 
getting patched to:

reg = <0x8 0x0134c000 0x1 0xda294000>
