[coreboot] Mohon Peak, Memtest86+ does not start

[Kuzmichev Viktor]

Yes, Martin Roth mentioned earlier about SeaBIOS not supporting serial 
input.

I've tried sgabios, but it looks like in order for it to work properly, 
I should disable all serial debug which is not very convenient.

However, in one of my latest e-mails I suggested that SeaBIOS should not 
control serial input in memtest since memtest has its own code for 
serial input handling. And still, input via serial console does not work 
in memtest. Any idea why that's the case?
