[coreboot] Jetw. J8F9 support

[Cristian Craciunescu]

Hello,

I've compiled suport for j8f9 board from jetw. using as template other LX
mainboard. The system is booting with coreboot/seabios however the serial
does not seam to work in kernel. GRUB bootloader works ok over serial but as
soon as the linux kernel finish booting it does not respond over serial but
it can send messages to serial. Although the IRQs are detected correctly
when the serial has input I can not see any irq messages incrementing in
/proc/interrupts. Any hint?

Regards,
Cristian
