Well it's not complete clear where we want to go with this. My current
thinking is that the emulated memory will be small (in 2011 terms) -
maybe 128MB. The real memory of the machine is not accessible since it
doesn't make sense. So perhaps just because the host happens to be a
64-bit machine we don't suddenly want to be printing 64-bit addresses.

So the answer is 'yes' but for now I'm not sure that's the right thing
to do. I have another patch which enables 'md', etc. but of course
only within the 128MB 'emulated' memory area.

It actually brings up a question - does U-Boot run on 64-machines?

Regards,
Simon
