As a consumer, I wrote to AMD for expressing my concern:
*** Dear Sir,
Recently I adquired a Compulab fitlet B computer made of your motherboard. This product comes with a propietary BIOS and I plan to install a free one: Coreboot. But unfortunately I am not able to do that because you do not provide binaryPI information in order that Coreboot could support it [1].
As a consumer, please get into contact to Coreboot (http://www.coreboot.org) for solving this issue.
I'm looking forward to hear news from you.
Regards, Xavier Garcia.
