Tom, these are the OSPI phy calibration patterns. I added them as they
are in the J721e u-boot.dtsi and both use the same OSPI interface.
However, I dug into this more and the upstream Cadence OSPI driver isn't
calibrating the phys.
I will respin this series to remove the .dtsi nodes, and add a patch to
the J721e series to remove it from there as well.
Thanks for catching.
