There were some old bugs which caused the wrong board description to
be picked up, the seems similar.

can't be sure.

Did you also update the meta and machine branch SRCREVs ?

Start with the yocto-bsp tool, it's probably the easiest way to define a
new BSP in recipe space, and then move it to the kernel later.
