Please try the existing series and if possible review it instead of
sending a new conflicting series :-)

The plan is to use a single rock5b defconfig target for both 5B and 5B+.
And in the future the ROCK 5T should also be able to the same target.

The latest ddr bin from rkbin at the time when my series was sent back
in July and August when my series was sent, should have been the
v1.19.bin blob. Did you have an issue with a TPL blob using my series?

With my series applied you should be able to build the rock5b target
and when booting on a 5B+ you should be able to see something like

  Model: Radxa ROCK 5B+
  SoC:   RK3588

and this will indicate that the 5B+ device tree is correctly used.

Regards,
Jonas
