We (Xilinx) are consolidating a meta-xilinx layer that will include BSP support for our popular boards - ZC702, 706, ZedBoard etc.  The plan for now is that these BSPs will include prebuilt FSBL images so that a user can boot something without a Xilinx tool install etc.

I'm looking forward to testing this. Hopefully, I can use it the same
way I use my current meta-zynq, by using bbappends to the kernel recipe
to modify the kernel in the base BSP. This was you can add your specific
board specific logic in a separate layer.
