store every HT device unit id base and pass those info to acpi https://openbios.org/roundup/linuxbios/issue46 Note: This version drops the two scripts a and c and creates the dsdt on the fly from Config.lb using makerule git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2134 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
