Hi Michal,

This would be because U-Boot is being built for MIPS64r2 whilst QEMU is 
emulating the MIPS64r6-implementing I6400, and MIPSr6 isn't entirely 
backwards compatible with MIPSr2. If you reconfigure U-Boot to build for 
MIPS64r6 then you should find that it runs correctly. I'll add mention 
of that to the README file.

Thanks,
     Paul
