Agreed.

Patches v7 #1 through #4 should be merged, because they were posted
before the SFF, and they already carried an R-b from Liming (MdePkg
co-maintainer).

Patches #5 and #6 seem to have been superseded by the following separate
series:

  [edk2-devel] [PATCH 0/2] Add FMP Capsule Image Header extension
  https://edk2.groups.io/g/devel/message/59652
  http://mid.mail-archive.com/20200515073848.13920-1-wei6.xu@intel.com

Now, this separate series was also posted (even if barely: 22 minutes)
before the SFF. The patches also contained some R-b tags upon posting.

Patch #1 had an R-b from Liming, upon posting. The files it modifies are:
- MdeModulePkg/Application/CapsuleApp/CapsuleDump.c
- MdeModulePkg/Library/DxeCapsuleLibFmp/DxeCapsuleLib.c

I've run "BaseTools/Scripts/GetMaintainer.py" with the "-l" option on
both files. Both invocations list Liming as a designated reviewer. (From
section "MdeModulePkg: Firmware Update modules", as far as I can tell.)

Patch #2 had an R-b from Liming and Chao Zhang, on posting. The patch
modifies the following file:
- SignedCapsulePkg/Universal/RecoveryModuleLoadPei/RecoveryModuleLoadPei.c

"GetMaintainer.py" does list "Chao Zhang" with the "-l" option. (See the
"SignedCapsulePkg" section in Maintainers.txt".)

So, assuming both patches included those R-b's *justifiedly* when there
were posted (that is, the R-b's were given earlier on the list), I think
this 2-part series too should be merged. Technically speaking, it was
fully reviewed as soon as it was posted, and it was posted in time.

I think even a v4 would be eligible for merging (with the commit message
improvements that you are suggesting). Even during the hard feature
freeze. (Possibly justifying an extension to the hard feature freeze.)

Here's why I think that:
<https://bugzilla.tianocore.org/show_bug.cgi?id=2713#c0> is a good issue
report. It explains that this patch is a bugfix. Namely, commit
710174e01174 ("SecurityPkg: Tcg2PhysicalPresence: Define TCG2 PP Flags
Initial Pcd", 2016-12-29) was incomplete; it created an inconsistency in
physical presence flag defaults, between different code paths. And the
new patch fixes that.

(On the negative side, three versions of the patch have been posted to
the list, and the bugzilla ticket has pointers to... none of those. The
last comment remains, at this time, "Still investigate the solution to
fix it". I find that really frustrating and sad.)

Thanks,
Laszlo
