Re: 'fastboot boot' TPL

Are you sure?

If you look at this file:
https://github.com/tianocore/edk2/blob/master/EmbeddedPkg/Application/AndroidFastboot/AndroidFastbootApp.c

The DataReady Event is a TPL_CALLBACK event.
>From there the call chain goes as follows:
AcceptCmd -> HandleBoot -> BootAndroidBootImg -> StartEfiApplication ->
"gBS->StartImage"

Thanks
