Revision: linuxbios@linuxbios.org--devel/freebios--devel--2.0--patch-3
Creator: Eric Biederman <ebiederman@lnxi.com> Add read[bwl] write[bwl] to arch/io.h for i386 A pending patch requires needs this and ppc already has them so it is a good idea to implement them :) I don't know why this was not implemented earlier. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1922 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
