Change subject: soc/intel/braswell: Add support for FSP MR2
......................................................................

Patch Set 2:
> Patch Set 2:

> FSP MR2 seems to not be compatible (is it possible!?) with the braswell SoC I have:
> Intel Atom x5-E8000 CPU 1.04GHz 
> Cpuid 000406c4 cpus 4 rid 35 step D1
>
> Although FPS signature and revision is detected well:

> FSP Signature: BSWSBFSP
> FSP Header Version: 2
> FSP Revision: 1.1.4.1

> I'm stuck at post FSP MemoryInit (0x92). I have to stick to older FSP I guess. I have also checked whether I use the unsupported UPD values, but it is not the case. Is it supported only on CherryChill CRB?

Portwell M107 used same CPU, where it works fine.
