Issue #401 has been updated by Christian Walter.

Is this a problem within coreboot - or do we rather need to fix up EDKII ?

----------------------------------------
Bug #401: edk2 hangs indefiniately 
https://ticket.coreboot.org/issues/401#change-1043

* Author: Sean Rhodes
* Status: New
* Priority: Normal
* Assignee: Arthur Heymans
* Category: board support
* Target version: none
* Start date: 2022-07-08
* Affected versions: master
* Affected hardware: Everything
* Affected OS: Doesn't matter
----------------------------------------
Since CB:63555, edk2 will no longer boot and hangs indefiniately

Various forks disable MTRR programming in edk2 (such as 
https://github.com/MrChromebox/edk2/commit/d641ea6920737fd9b9a94210e9a2e7636bfb3cdc)
 but this shouldn't be done as it breaks spec.

Workarounds are to revert CB:64804, CB:63550, CB:64803 and CB:63555.
