[coreboot] Blobless coreboot on Sandy Bridge and Ivy Bridge?

[Thomasheidler]

If one excludes any microcode and the VGA BIOS, is it possible to build a functioning, blobless coreboot for any Sandy Bridge or Ivy Bridge device supported? I'm referring here only to the BIOS region on the flash, not the ME region, IFD and GbE. If the FSP blob is needed, would that be the only blob required?

Thanks
