It's not really doing the wrong thing, it's just sort of outdated and
not doing what I guess you'd expect, which is to match the reference
board in meta-yocto-bsp (note that the yocto-bsp tool doesn't really
have anything to do with meta-yocto-bsp, though the names are similar).

The old arm reference board was the beagleboard, and that's what the
yocto-bsp template reflects, and should probably be updated to use the
beaglebone settings.

I'd suggest just manually modifying the generated BSP to match your
hardware; technically the output of yocto-bsp is only guaranteed to
build, not necessarily successfully boot on a given board.  The Intel
boards have been boot-tested, but that's just because I have the
necessary hardware, and nobody's actually paid much attention to the arm
output, as far as I can tell.  If you have suggestions other than that
that the output should match the beaglebone reference in meta-yocto-bsp,
I'd be happy to make those changes in the next iteration of the tool.

Thanks,

Tom
