> Should a new intermediate bus layer also do byte swapping?
Yes, though a bus layer isn't actually a necessary prerequisite.
As I mentioned in the recent "Smarter compilation for target devices"
thread[1], having individual devices do byteswapping is bogus. A while ago I
reworked the TLB handling, so there should now be spare bits that can be used
for things like byteswapping.
