I am fairly certain the physical address is correct, I've verified that the
TLB entries in u-boot look ok. Any tips on how to make this work?
I found / fixed the issue. The first problem is that start and offset
are swapped in the io_remap_pfn_range invocation. The 2nd was that
there were some TLB changes that were needed to map the OCM.
