[meta-xilinx] Clarification on pmu_cfg_obj handling for zynqmp boards

[Scott Ellis]

Hi Manju,

Thanks for answering.

I will look at the meta-xilinx-tools layer. I think I finally understand
what is required to boot.

But I am still not clear on the meta-xilinx multiconfig...

The meta-xilinx-bsp/README.building.md has no mention that a patch is
required to the pmu-firmware which is confusing.

Is this just an omission?

Is the pmu-firmware recipe useful without the patch?

Excuse the dumb questions.

I am new to xilinx boards.

Regards,
Scott
