---------------------------------------- Bug #401: edk2 hangs indefiniately https://ticket.coreboot.org/issues/401#change-1035
* 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/d641ea6920737fd9b9a94210e9a2e7636...) but this shouldn't be done as it breaks spec.
Workarounds are to revert CB:64804, CB:63550, CB:64803 and CB:63555.
