A couple of things:

Version is still different, but I would be surprised if this is the problem:

-Linux version 4.9.88 (tom@buildroot) (gcc version 6.4.0 (Buildroot 2018.05-git-01173-gba1f416507) ) #1 SMP PREEMPT RT Thu May 3 20:46:07 UTC 2018

Then the PRUs just show up:

Is there a kconfig file of the other kernel?

WTF is this...
Look at the diff of dtb again?

Maybe this is in the overlays..
How to save the exact config as a device tree file?

Get a full device tree from the filesystem:

sudo apt-get install device-tree-compiler
dtc -I fs -O dts /sys/firmware/devicetree/base


tom@panda:~$ ssh root@bb49 dtc -I fs -O dts /sys/firmware/devicetree/base >bb49.dts
tom@panda:~$ dtc -I dtb -O dts bbbr.dtb >bbbr.dts

Yeah diff is huge.  I need to take a closer look at how bb49 boots up.
