new thinkpad's can't be used anymore for coreboot. Especially the U and
Y Intel CPU Series.
They come with Intel Boot Guard and you are won't be able to boot
anything which is unsigned and
not approved by OEM. This means the OEM are fusing SHA256 public key
hashes into the southbridge.

For more details take a look at Intel Boot Guard architecture. It could
be also confirmed by Secunet AG and Google.
