Hi,
Right, sorry, I confused something while writing the explanation there. Nevertheless, the SeaBIOS code will require a small adjustment (same as the libpayload driver in the patch I linked) to continue appending correctly after the log has rolled over, and I'll provide that patch.
Is it possible to figure whenever the cbmem buffer supports rollover or not, so a updated seabios version can work correctly with both old and new coreboot?
cheers, Gerd
