barebox fb console on an EFI system

Hi,

I'm working on an EFI embedded system, actually a standard PC, with a
display and a USB keyboard connected to it.

The bootloader I'm using is a barebox 2017.09.0 configured with
'arch/x86/configs/efi_defconfig'.

What I notice is that if both config options:

FRAMEBUFFER_CONSOLE and DRIVER_VIDEO_EFI_GOP

are enabled then, at runtime, I see two video consoles at the same time
on the display: one console takes the whole display area, the other is smaller.

If I just activate one of the previous options or if I disable both then I just see
the smaller console on the display.

Moreover, if I disable the option

 DRIVER_SERIAL_EFI_STDIO

then I just see the 'bigger' console, as I want to, but unfortunately the
keyboard does not work anymore.

I think here there is some unwanted interaction at play.
