You may specify '-d bus:dev.func' or '-d dev.func'. If you do '-d <value>' then the behavior reverts back to the orginal where <value> is taken to be the 16-bit packed notation of busdevfn. It also add a sanity check to try and detect when people have not specified the -d option and they should have, or when the -d bus:dev.fn evals to a packed busdevfn of 0x0000. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2271 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
