Dear Paul,

Unfortunatelly EDK2 does not work.

SeaBios works after setting serial port address with:
config option 'CONSOLE_UART_BASE_ADDRESS' to 0xA0019000
previously CONSOLE_UART_BASE_ADDRESS was empty, so SeaBIOS didn't know 
where to log data


Now the log from Galileo looks like this:

```

OK, I'll try to get logs over serial port from GRUB


Thanks for your support,
