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?
