Skylake FSP 1.1 POST codes and debug

Hello!

I'm trying to execute FSP 1.1 for Skylake (inside Coreboot) and got some problems with RamInit call. I'm fill UpdParams and calling RamInit - but system halted inside this function. Also I'm using LPC PORT80 card, and have some undetermined codes - perhaps it generated inside FPS RamInit function. Codes are: 0x27, 0x29, 0x4c, 0xff. May be have another codes, but my PORT80 card saves only 4 last values.

I can't find any description of this codes in Intel official documentation - so I need help with this.

Also, have another question about Skylake FSP. Can I use FSP with desctop Skylake? What RCOMP values must be used for DDR4 DRAM (in platform design guide this values not present)?
