From b257662e55c7904b0d6f50ad688a5b8423503604 Mon Sep 17 00:00:00 2001 From: Nicholas Chin Date: Sat, 26 Oct 2024 20:55:18 -0600 Subject: config/coreboot/default: Update MEC5035 patches - Update the MEC5035 S3 patches to the versions that were sent upstream to prevent conflicts with subsequent patches for that EC. - Update the patch that enables the S3 SMI handler in mainboard code so that all Latitudes use the handler. - Add a new patch that tells the EC to route power button events to the host so that the OS can decide what to do. Without it, the EC powers off the system without letting the OS cleanly shut down.
