I was thinking about this point over the weekend, and I realized
that it may not have been clear that I'm talking largely about
the kernel here. Not all the associated userspace/config, etc
that we'd consider as part of a complete solution. Obviously
any kernel tree can support multiple boards, and what we have
here is an example against the 2.6.37 yocto kernel tree and
kernel feature set.
