Thank you,

I finally get it to works. I tried to get the binary decoded and ran
started at higher address but without success since it seems that
address below 0x30000000  are considered outside RAM or ROM. 

So what I have done is changing the boot image location from 31000000 to
32000000. To achieve so I changed in hw/neo1973.c from qemu-neo
load_image(s->kernel, phys_ram_base + 0x01000000);
to
load_image(s->kernel, phys_ram_base + 0x02000000);
So it doesn't overlap anymore.
