From 3be34f5ba685c15e8537e4489589bf01ad7ea731 Mon Sep 17 00:00:00 2001

Subject: [PATCH 11/16] ArmVirtPkg: take PcdResizeXterm from the QEMU command
line (RH only)
Notes about the 20160608b-988715a -> 20170228-c325e41585e3 rebase:
- Adapt commit 6b97969096a3 to the fact that upstream has deprecated such
setter functions for dynamic PCDs that don't return a status code (such
as PcdSetBool()). Employ PcdSetBoolS(), and assert that it succeeds --
there's really no circumstance in this case when it could fail.
Notes about the 20170228-c325e41585e3 -> 20171011-92d07e48907f rebase:
- Refresh downstream-only commit d4564d39dfdb against context changes in
"ArmVirtPkg/ArmVirtQemu.dsc" from upstream commit 7e5f1b673870
("ArmVirtPkg/PlatformHasAcpiDtDxe: allow guest level ACPI disable
override", 2017-03-29).
