The linker address of course needs to be changed. Preventing the cpu 
accessing the FPGA OnChip RAM was a bit more tricky to debug, but it 
seems I have it working now.

I guess we need a Kconfig option to enable the bridge reset changes and 
select the correct link address. I'll prepare a patch for that. Should I 
base it on top of my gen5 fixes series?

Additionally, to add the binary into an fpga, we need a hex file, maybe 
these can be automatically generated by mach-socfpga's Makefile when 
creating the SPL...
