Subject: [PATCH 04/17] OvmfPkg: take PcdResizeXterm from the QEMU command line
 (RH only)

edk2-stable202205 rebase

- re-add UPDATE_BOOLEAN_PCD_FROM_FW_CFG
- add microvm, cloudhw and inteltdx

edk2-stable202108 rebase

- resolve conflict in OvmfPkg/PlatformPei/PlatformPei.inf

Notes about the RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] ->
RHEL-8.5/20210520-e1999b264f1f [edk2-stable202105] rebase:

- Extend the DSC change to the new OvmfPkg/AmdSev platform, which has been
  introduced upstream in commit 30d277ed7a82 ("OvmfPkg/Amdsev: Base commit
  to build encrypted boot specific OVMF", 2020-12-14), for TianoCore#3077.

  We've always patched all those DSC/FDF files in OvmfPkg down-stream that
  made sense at least in theory on QEMU. (For example, we've always
  patched "OvmfPkgIa32.dsc" and "OvmfPkgIa32.fdf", even though we never
  build or ship the pure IA32 firmware platform.) Follow suit with
  "AmdSevX64.dsc".

Notes about the RHEL-8.2/20190904-37eef91017ad [edk2-stable201908] ->
RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] rebase:

- Resolve contextual conflict in the DSC files, from upstream commit
  b0ed7ebdebd1 ("OvmfPkg: set fixed FlashNvStorage base addresses with -D
  SMM_REQUIRE", 2020-03-12).

Notes about the RHEL-8.1/20190308-89910a39dcfd [edk2-stable201903] ->
RHEL-8.2/20190904-37eef91017ad [edk2-stable201908] rebase:

- no change

Notes about the RHEL-8.0/20180508-ee3198e672e2 ->
RHEL-8.1/20190308-89910a39dcfd rebase:

- no change

Notes about the RHEL-7.6/ovmf-20180508-2.gitee3198e672e2.el7 ->
RHEL-8.0/20180508-ee3198e672e2 rebase:

- reorder the rebase changelog in the commit message so that it reads like
  a blog: place more recent entries near the top
- no changes to the patch body

Notes about the 20171011-92d07e48907f -> 20180508-ee3198e672e2 rebase:

- no change

Notes about the 20170228-c325e41585e3 -> 20171011-92d07e48907f rebase:

- refresh downstream-only commit 8abc2a6ddad2 against context differences
  in the DSC files from upstream commit 5e167d7e784c
  ("OvmfPkg/PlatformPei: don't allocate reserved mem varstore if
  SMM_REQUIRE", 2017-03-12).

Notes about the 20160608b-988715a -> 20170228-c325e41585e3 rebase:

- no changes
