Sorry not sure, I've only tested with QEMU which does not appear to
need the configuration? or at least it boots without it. I have not
looked at SD with QEMU though, and U-Boot throws card voltage select
errors and fails to probe it :|.

The only information i've found for this config object is some tcl and
template files in the embeddedsw repo.

https://github.com/Xilinx/embeddedsw/blob/master/lib/sw_services/xilpm/data/cfg_gen.tcl
https://github.com/Xilinx/embeddedsw/blob/master/lib/sw_services/xilpm/data/cfg_data.tpl

Which look like a code file generated from HDF data which is likely
embedded into FSBL. Looking at the ZCU102 PetaLinux BSP reveals as
much.
