Hi Coreboot team

i came across this article Board:lenovo/g505s - coreboot.

Is there a way to reflash the bios of KB9012 of this board using coreboot?   (it is EC bios and inbuilt)

This EC chip has become corrupt and I was wondering if at all coreboot had a solution for this . 
I was planning to go for the RT809F serial isp programmer, thought i might ask you guys first.

Great job,
thanks,
Harry
