It does appear to be slight better, although all platforms that I have 
where memory starts at physical address 0 cannot boot, attached logs 
which are all more or less the same.

The physical memory map looks like this:

0..3GB -> DRAM
3GB..4GB -> Registers, Boot ROM, Boot SRAM
4GB..12GB -> DRAM extension

Do any of the platforms you use for testing have a similar memory map? 
Could you try to contrive a QEMU machine to have something similar in 
case that helps reproducing these failures?

Thanks
