So can we determine the "right" value of RAMTOP? I think the only unknown is stack usage. Actually, I guess you could calculate it right now, since stack size is a parameter. Something like code + data + stack + padding to make it an even amount = RAMTOP. Thanks, Myles -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
