Subject: ArmVirtPkg: take PcdResizeXterm from the QEMU command line (RH only)
Notes about the RHEL-8.2/20190904-37eef91017ad [edk2-stable201908] ->
RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] rebase:
- Resolve leading context divergence in "ArmVirtPkg/ArmVirtQemu.dsc",
arising from upstream commits:
- 82662a3b5f56 ("ArmVirtPkg/PlatformPeiLib: discover the TPM base
address from the DT", 2020-03-04)
- ddd34a818315 ("ArmVirtPkg/ArmVirtQemu: enable TPM2 support in the PEI
phase", 2020-03-04)
- cdc3fa54184a ("ArmVirtPkg: control PXEv4 / PXEv6 boot support from the
QEMU command line", 2020-04-28)
- Rework the downstream patch quite a bit, paralleling the upstream work
done for <https://bugzilla.tianocore.org/show_bug.cgi?id=2681> in commit
range 64ab457d1f21..cdc3fa54184a:
- Refresh copyright year in TerminalPcdProducerLib.{inf,c}. Also replace
open-coded BSDL with "SPDX-License-Identifier: BSD-2-Clause-Patent".
- Simplify LIBRARY_CLASS: this lib instance is meant to be consumed only
via NULL class resolution (basically: as a plugin), so use NULL for
LIBRARY_CLASS, not "TerminalPcdProducerLib|DXE_DRIVER".
- Sort the [Packages] section alphabetically in the INF file.
- Replace the open-coded GetNamedFwCfgBoolean() function with a call to
QemuFwCfgParseBool(), from QemuFwCfgSimpleParserLib.
- Add the SOMETIMES_PRODUCES usage comment in the [Pcd] section of the
INF file.
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 d4564d39dfdb against context changes in
"ArmVirtPkg/ArmVirtQemu.dsc" from upstream commit 7e5f1b673870
("ArmVirtPkg/PlatformHasAcpiDtDxe: allow guest level ACPI disable
override", 2017-03-29).
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.
