From 23d3998ad5c8216a99cfcf599a36e4db4e716323 Mon Sep 17 00:00:00 2001 From: andrewfish Date: Tue, 18 May 2010 00:54:24 +0000 Subject: Remove DebugSupport driver for ARM and DebugSupportProtocol. In edk2 you can link debugger into DXE core directly so you don't need a debug support. Also we are going to FIQ for debugger ctrl-c break in, so no need to hook the timer infrastructure. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10495 6f19259b-4bc3-4df7-8a09-765794883524 --- EmbeddedPkg/DebugSupportDxe/DebugSupport.c | 119 ------------------------ EmbeddedPkg/DebugSupportDxe/DebugSupportDxe.inf | 40 -------- 2 files changed, 159 deletions(-) delete mode 100644 EmbeddedPkg/DebugSupportDxe/DebugSupport.c delete mode 100644 EmbeddedPkg/DebugSupportDxe/DebugSupportDxe.inf (limited to 'EmbeddedPkg') diff --git a/EmbeddedPkg/DebugSupportDxe/DebugSupport.c b/EmbeddedPkg/DebugSupportDxe/DebugSupport.c deleted file mode 100644 index 5498aabc75..0000000000 --- a/EmbeddedPkg/DebugSupportDxe/DebugSupport.c +++ /dev/null @@ -1,119 +0,0 @@ -/** @file - - Copyright (c) 2008 - 2009, Apple Inc.
