commit fba913f1a4aceea19bb00fe3c02fe316bd6aa056 Author: Aaron Durbin adurbin@chromium.org Date: Wed Sep 2 09:21:36 2015 -0500
bootmode: add display_init_required()
Some of the Chrome OS boards were directly calling vboot called in some form after contorting around #ifdef preprocessor macros. The reasoning is that Chrome OS doesn't always do display initialization during startup. It's runtime dependent. While this is a requirement that doesn't mean vboot functions should be sprinkled around in the mainboard and chipset code. Instead provide one function, display_init_required(), that provides the policy for determining display initialization action. For Chrome OS devices this function honors vboot_skip_display_init() and all other configurations default to initializing display.
