I just tested the same revisions as you mentioned and the board boot for
me. How do you test the board? Over serial?

If you are using serial I suspecte you are not setting the serial
console. if you are using tty1 (hdmi) you need to add the specific
console argument to cmdline.

What do you mean rpi is not following the yocto project naming
convention? It does miss a branch for the last yocto release but there
are already for the old ones.
