From 586cd1f1f4129ab7ec24543d4968801e17cc870b Mon Sep 17 00:00:00 2001 From: lhauch Date: Fri, 1 Jun 2007 14:49:55 +0000 Subject: Moved the MdePkg to OldMdePkg so that new code in MdePkg does not break existing builds. Also updated the SPD and FPD files UiNames git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@2616 6f19259b-4bc3-4df7-8a09-765794883524 --- .../UefiDevicePathLib.c | 348 --------------------- 1 file changed, 348 deletions(-) delete mode 100644 MdePkg/Library/UefiDevicePathLibDevicePathProtocol/UefiDevicePathLib.c (limited to 'MdePkg/Library/UefiDevicePathLibDevicePathProtocol/UefiDevicePathLib.c') diff --git a/MdePkg/Library/UefiDevicePathLibDevicePathProtocol/UefiDevicePathLib.c b/MdePkg/Library/UefiDevicePathLibDevicePathProtocol/UefiDevicePathLib.c deleted file mode 100644 index ec9b4aa321..0000000000 --- a/MdePkg/Library/UefiDevicePathLibDevicePathProtocol/UefiDevicePathLib.c +++ /dev/null @@ -1,348 +0,0 @@ -/** @file - UEFI Device Path Library. - - Copyright (c) 2006, Intel Corporation
