From 98449a1678f46047098a3d0186af4f6022fdc824 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Fri, 9 Nov 2018 19:43:55 +0100 Subject: [PATCH] Reapply "OvmfPkg: VMWare SVGA display device register definitions" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit 328409ce8de7f318ee9c929b64302bd361cd1dbd, reapplying 9bcca53fe466cdff397578328d9d87d257aba493. Note that the commit now being reverted is technically correct; the only reason we're reverting it is because it should not have been pushed past the Soft Feature Freeze for the edk2-stable201811 tag.
