[meta-xilinx] Inspecting AXI Speeds

[Giordon Stark]

Hi Matteo,

I'd like to (and more generally) benchmark various features of the ZCU102
evaluation board. Right now, I've used meta-xilinx to compile an OS that
has python. It would be great to figure out how to measure the AXI bus
speed (such as using DMA) by running a script on the OS. It's not clear to
me where to start or if the default image for the evaluation board will let
me do this (I believe it has the necessary drivers).
