  This series adds flash partition description through DT, currently
the flash partitions for J7 platforms is described through the mtdparts
commandline parameter passed from bootloader, this requires maintenance
of the partition information in a mtdparts string which is error prone.

Once the flash partitions are described through DT, the support for
mtdparts can be removed for these platforms from u-boot also.

Please address the feedback in [1] prior to adding the partitions? and
could you ensure it is done for all the impacted k3 SoCs?

I will do both of these in corresponding next revisions.
