I've just tried to reproduce this using a fresh clone of poky and
meta-raspberrypi on the morty branch. I edited bblayers.conf to add
the meta-raspberrypi layer and then edited local.conf to set MACHINE =
"raspberrypi3", those were my only changes. I then ran "bitbake
rpi-hwup-image" and it's correctly parsed all the recipes and started
the build.

Which exact commits of poky and meta-raspberrypi are you using? I have
the following:

meta
meta-poky
meta-yocto-bsp    = "morty:924e576b8930fd2268d85f0b151e5f68a3c2afce"
meta-raspberrypi  = "morty:28d4404f89eb59d406b4976c0e3f5ca19137ba74"
