Re: [edk2-devel] [PATCH] UefiPayloadPkg/PlatformBootManager: Connect console after EndOfDxe

["Wang, Sunny (HPS SW)" <sunnywang@hpe.com>]

Sorry for the delay.
Thanks for clarifying and further checking this, Dong.
I think some platforms in https://github.com/tianocore/edk2-platforms would do this before EndOfDxe. 
Yeah, I agree with Dong. If UefiPayloadPkg doesn't support trusted console and may not support it in the future, I also think it's fine to have this change.

Trusted console is required for TCG Physical Presence and only trusted console could be connected before EndOfDxe. Since TCG Physical Presence is not enabled yet in the UefiPayloadPkg, I think it is ok to have this change.
