Hi

I am going to go back on what I said earlier. The online discussion
seems to indicate that the BCM2836 has the same peripherals
as the BCM2835 on the previous Pi Models. But they are at
physical address 0x3F000000 rather than the 0x20000000.
The CPU core is a different ARM level.

Since people are having luck on the net and the source
for Linux can always be consulted if there are specific
register issues we can't figure out, I *THINK* that a
BSP variant for this makes sense as a GSoC project.

That would be an additional project to bring up the single
core as step 1, support SMP and test drivers done on other
single core Pi project. Maybe by the end of the summer ,
both can be supported with the same driver set.
