[U-Boot] Weird issues with u-boot on Microblaze

FIT support is not in mainline u-boot. Only in my testing repository.

Yes the same thing as with FIT. Not in mainline yet. Simple no time. But
I have patches in my tree and I want to send them to next merge open window.

I'll test it.

I have fix for u-boot bsp which fix it. The same issue is for uart16550.

I am going to update my git repo at http://git.monstr.eu/git/gitweb.cgi
There will be updated u-boot bsp too.

Thanks,
Michal
