From 23ab8df01a2c64fcb2eea5300c7b7a43baeba821 Mon Sep 17 00:00:00 2001 From: Pete Batard Date: Mon, 14 Oct 2019 16:03:11 +0100 Subject: [PATCH] ArmVirtPkg/PlatformBootManagerLib: Don't update progress if Pcd is 0 BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2266 Similar to what we now do for OVMF, we need to consider the possibility that PlatformBootManagerWaitCallback () may be called with a PcdPlatformBootTimeOut that was set to zero, in which case the call should simply return. We also change the initial timeout variable name to make the code explicit.
