From acd73b7ca287fa4fa2768550f0cab9394f07f964 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marvin=20Ha=CC=88user?= <8659494+mhaeuser@users.noreply.github.com> Date: Wed, 8 Mar 2023 17:25:27 +0100 Subject: [PATCH] BaseTools/DevicePath: Consume MdePkg/UefiDevicePathLib MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BaseTools has been duplicating and adapting code that is defined in MdePkg and MdeModulePkg. This leads to desync issues where the same symbols may be backed by different functions with slightly different semantics and also fixes that apply only to BaseTools or only to MdePkg and MdeModulePkg. To address these issues, update BaseTools/Source/C to utilize the code from MdePkg and MdeModulePkg.
