TODO - x86emu need (imo) some common header with prototypes at least - clog2, ulzma, hardwaremain prototypes added by this patch probably should be moved to some header too. - in src/devices/device_util.c prototype is before function because seems, it is used only within same file, if not it should be moved to debug section of prototypes in include/device/device.h Signed-off-by: Maciej Pijanka <maciej.pijanka@gmail.com> Acked-by: Myles Watson <mylesgw@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4871 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
