I'm trying to get Tianocore to work with my Thinkpad T400, however, the person I am working with, MrChromeBox, needs debugging information. The laptop is limited in ports, and the optimal solution according to them would be to use Coreboots CBMEM console. Neither Myself nor MrChromeBox know how to implement this, and it would be appreciated if someone more knowledgeable could implement this feature to correct whatever the error may be with the device and Tianocore.
