From 5e8286bed6f18cd2a85b029911f97da21b38394d Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 28 Apr 2015 15:59:12 -0500 Subject: program loading: add optional is_loader_active() callback Add a way for a loader to indicate if it is active. Such users of this callback would be vboot which can indicate to the rest of the system that it isn't active. is_loader_active() also gives vboot a chance to perform the necessary work to make said decision.
