[coreboot] SeaBios serial(RX) is not running.

[김유석 책임연구원]

Dear Sir.


Thank's your advise. everytime.


*Finially*, I was succsss the boot using coreboot.


But I have a *little problem.*


_*I'm can't typing throuth the serial.*_


My x86 BOX is only support serial console.


So, Serial console is very important.


*But **t**he **Sea**Bios is **Serial RX is fail*. I guess.


     Coreboot => TX OK

     SeaBios => TX OK. *RX Fail*

     GRUB2 => TX OK, RX OK.

     Linux(ubuntu 15.04) => TX OK, RX OK.


*TX OK* => Can see the log message throught the serial console.

*RX F**ail* => Can not typing throught the serial console.


I'm try to change the bootloader SeaBios to U-boot. and *U-boot is a TX, 
RX OK.*


Serial RX fail is a just SeaBios problem(Not HW issue). I guess.(Vendor 
builded coreboot(SeaBios) is TX/RX OK)


Please advise to me.


Thank you.
