Subject: [edk2-devel] [PATCH] MdeModulePkg: Retrive boot manager menu
from any fv

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3384

Currently, UefiBootManagerLib has the below assumption:
Assume the BootManagerMenuFile is in the same FV as the module links to
this library.
It has some limitation now, so remove the assumption.

Hello Zhiguang,

Sorry for a question. Do you know what is the boot performance impact if 'GetSectionFromAnyFv()' is being used?
Any data on the impact for originally working platforms?

Best Regards,
Hao Wu
