From 83f0a7c7b265a56d757f7e3a80622e5b0b7ebc46 Mon Sep 17 00:00:00 2001 From: Shunyong Yang Date: Fri, 4 May 2018 08:00:02 +0200 Subject: efi/capsule-loader: Don't output reset log when reset flags are not set When reset flags in capsule header are not set, it means firmware attempts to immediately process or launch the capsule. Moreover, reset is not needed in this case. The current code will output log to indicate reset. This patch adds a branch to avoid reset log output when the flags are not set.
