Coreboot has native x86 code to fully initialize sandy bridge without
blobs. Even the VGA bios can be replaced with existing native graphic
init (C code for LVDS or libgfxinit for every display output).

There is an FSP path for sandy bridge but it is not used much due to
native code being easier to work with.
