[meta-xilinx] Yocto fo Pynq Z1?

[Matthew Clark]

 I completely agree.  I was genuinely surprised to find no Yocto recipe for
it.  I'm willing to give it a spin, though.

The device tree was trivial.  I just ran "dtc" against /proc/device-tree on
the Ubuntu distro.  Bam.

Same for the kernel config.  /proc/config.gz

It's the stuff in
rel-v2018.1/sources/meta-xilinx/meta-xilinx-bsp/conf/machine that has me a
bit flumoxed.  I want to use one as a starting point, but no clue which one
since there are a lot of "overrides", etc.

What would anyone suggest?

Matt
