[coreboot] it8712f patch

[Andy Jakobs]

Dear Marc,

I am happy, that there is still work on the A8N-E, as I own such a board.

Unfortunately the PS/2 keyboard port is not working yet (see also build 
tutorial from the wiki).

I already applied your patch and it ended in a grub or filo shell.

 From a second PC I can access the filo shell and type in commands over 
minicom.
For grub2 this does not work.

So do you have an instruction for me, how to test that your patch is 
successfull?

Do you need the minicom log?

BR,
Andy
