Subject: OvmfPkg: silence DEBUG_VERBOSE (0x00400000) in
 QemuVideoDxe/QemuRamfbDxe (RH)

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

- Due to upstream commit 4b04d9d73604 ("OvmfPkg: Don't build in
  QemuVideoDxe when we have CSM", 2019-06-26), the contexts of
  "QemuVideoDxe.inf" / "QemuRamfbDxe.inf" have changed in the DSC files.
  Resolve the conflict manually.

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

- Upstream commit 1d25ff51af5c ("OvmfPkg: add QemuRamfbDxe", 2018-06-14)
  introduced another GOP driver that consumes FrameBufferBltLib, and
  thereby produces a large number of (mostly useless) debug messages at
  the DEBUG_VERBOSE level. Extend the patch to suppress those messages in
  both QemuVideoDxe and QemuRamfbDxe; update the subject accordingly.
  QemuRamfbDxe itself doesn't log anything at the VERBOSE level (see also
  the original commit message at the bottom of this downstream patch).

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 changes

O-Subject:  [PATCH 5/7] OvmfPkg: silence EFI_D_VERBOSE (0x00400000) in
	QemuVideoDxe (RH only)
Bugzilla: 1488247
Acked-by: Laszlo Ersek <lersek@redhat.com>
Acked-by: Thomas Huth <thuth@redhat.com>

From: Laszlo Ersek <lersek@redhat.com>

In commit 5b2291f9567a ("OvmfPkg: QemuVideoDxe uses
MdeModulePkg/FrameBufferLib"), QemuVideoDxe was rebased to
FrameBufferBltLib.

The FrameBufferBltLib instance added in commit b1ca386074bd
("MdeModulePkg: Add FrameBufferBltLib library instance") logs many
messages on the VERBOSE level; for example, a normal boot with OVMF can
produce 500+ "VideoFill" messages, dependent on the progress bar, when the
VERBOSE bit is set in PcdDebugPrintErrorLevel.

QemuVideoDxe itself doesn't log anything at the VERBOSE level, so we lose
none of its messages this way.
