Hi Simon,

  is your testing framework connected to HDMI? Only notable discrepancy
from generic config is enabled 'efidebug' command.


Tested more (cycled 'U-Boot>' and 'reset'), both RPi3B and RPi3B+..
USB Keyboard failure rates:
connected console            02/10
connected hdmi               06/10
connected console + hdmi     07/10
** USB Keyboard always detected by 'usb info', just does not respond.

USB Keyboard failure rates, reverted 96991e652f541323a03c5b7e075d54a117091618:
connected console + hdmi     00/10



  Just to note subsequent Grub2 menu redraw to my 180x50 console terminal
is about 5x faster when hdmi disconnected.



Thanks for testing!
Regards,
Filip
