From 143f0b1de83257f1bd238f016bba955879d448c2 Mon Sep 17 00:00:00 2001 From: Eric Dong Date: Thu, 30 Jul 2015 03:41:35 +0000 Subject: UiApp code split from IntelFrameworkModulePkg/Universal/BdsDxe driver. This is the UI part of the old BdsDxe driver, also remove the legacy boot option related code.
