From b057be47f732b86496e2c1b997972d31953a1198 Mon Sep 17 00:00:00 2001 From: Jeff Fan Date: Mon, 18 May 2015 01:21:30 +0000 Subject: SourceLevelDebugPkg/DebugAgentDxe: Move help info from DxeDebugAgent Now DxeDebugAgent Library instance will print help information on how to load DebugAgentDxe.efi in UEFI shell. But it is printed after Target connected to Host side. This fix is to move help info print to DebugAgentDxe module before Target tries to connect HOST. It could help developer to get useful information as early as possible.
