Hi Mike,
Some MINOR comments at my first sight.
1. Should *.uni and *Extra.uni be added for this module?
2. Could EfiCreateEventReadyToBootEx() be used instead of below code? Then gEfiEventReadyToBootGuid reference in *.inf could be also removed.
+ Status = gBS->CreateEventEx (
+ EVT_NOTIFY_SIGNAL,
+ TPL_CALLBACK,
+ EsrtReadyToBootEventNotify,
+ NULL,
+ &gEfiEventReadyToBootGuid,
+ &mEsrtReadyToBootEvent
+ );
3. Is it better to have the MODULE_TYPE to be DXE_DRIVER?
+ MODULE_TYPE = UEFI_DRIVER
Thanks,
Star

Subject: [edk2] [Patch 1/3] MdeModulePkg/EsrtFmpDxe: Add EsrtFmpDxe module
From: Michael D Kinney <michael.d.kinney@intel.com>
https://bugzilla.tianocore.org/show_bug.cgi?id=802
Based on content from the following branch/commits:
https://github.com/Microsoft/MS_UEFI/tree/share/MsCapsuleSupport
The EsrtFmpDxe module is a lightweight version of the EsrtDxe module that produces ESRT entries based only on FMP Protocol instances.

Ray,
I preserved the BSD 2-clause license style that was
used in the MS_UEFI repository that this patch is based
on.
The license header in most files in the edk2 repository
provide a link to the BSD 2-clause license and are also
covered by the License.txt file in the root of the edk2
repository.
For most new content, we prefer the style used for most
of the edk2 repository.
For content that is imported from other sources, the
the original license text is preserved.
