That looks good, yes.
Is 0x10000 the correct maximum addressable size of the external bus
in both cases?
Intuitively, I would guess that the 0xa0000000 range might
be much wider.

I don't see the audio and spi nodes, so I'm not sure where exactly
you would put them.
Ideally those things should be visible from a block diagram in the
datasheet.
