Hi!

I have good news and bad news.

The good news is that erizo barebox successfully runs on real FPGA hardware.

The bad news is that there is no "stack" region in erizo iomem output;
also barebox relocated to te middle of RAM not to the top of RAM:

barebox:/ iomem
0x00000000 - 0xffffffff (size 0x00000000) iomem
  0x80000000 - 0x807fffff (size 0x00800000) ram0

Please compare with mips malta and arm vexpress-a9 iomem output:
