Applying U-boot overlay from the command line?

In the past, I'd apply an overlay by catting some stuff to .../slots. That no longer shows up in my sysfs.

I'm working on a U-boot overlay, but while experimenting, is there a way to apply the overlay from the command line after boot?

Nope all done in /boot/uEnv.txt on boot

Okay thanks.

Actually, there is a way, Jason K figured this out late last week and
it has not been fully documented out side of the e-ale.org training yet...

We haven't figured out how far back this goes with mainline kernels
but, create a directory under:

/sys/kernel/config/device-tree/overlays/

Like:

sudo mkdir -p /sys/kernel/config/device-tree/overlays/accel/

then just echo the *.dtbo into the ./dtbo file created in the directory above..
