Subject: [PATCH 9/9] mb/purism/librem_skl: disable HECI PCI device
|
|
|
|
As all librem_skl devices ship with the ME disabled via HAP bit and ME
|
|
firmware "neutralized" via me_cleaner, the HECI1 PCI device should be
|
|
marked off/disabled to ensure that heci_reset() is not called at the end
|
|
of heci_init(), as this causes a 15s timeout delay when booting
|
|
(introduced in commit cb2fd20 [soc/intel/common: Add HECI Reset flow in
|
|
the CSE driver]).
