I'm not sure if we should rename all of these right now. I've been thinking
about moving all of recent and simple ARMv7 based platforms (socfpga, zynq,
prima2, ...) into a single directory, where they would basically end up
being one file per platform. We should discuss this at the ARM mini summit,
and I can let you know the outcome of it. I don't object on the rename in
principle, but it might end up causing extra churn.

I'm curious about this: I did read that Samsung acquired CSR, and
you list the chips as Qualcomm. What's the story here?

Is this still needed? When you add other SoC type here, would you
build kernels that are for just one of them in practice?  If they
are completely generic anyway, you can skip the submenu.
