New subject: Plans for upcoming Broadwell Thinkpads

7 Feb 2015

Hi,

let's say goodbye to all Intel notebooks produced by OEM's which are not
Google ( Chromebooks ). Maybe the haswell/broadwell notebooks of Lenovo
without U/Y processor can be used ( Thinkpad tXX xXX ). It depends if
they are supporting Intel Boot Guard on the southbridge...

 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.

 That's scary to say the least.  No more Thinkpads for us...
