Thank you for adding this / looking forward to improve cooperation in the future.

Long names of board and kernels stands out. Name of the device is the name, while kernel can easily be codified into something shorter (beagle2, pb2, ...). It will only be in use for this device and hopefully not very long.

Thanks Igor! Shortened the names to just be PocketBeagle 2 and beagle-edge for Kernel for now.

There will be some cleanup done soon on the Beagle side and we'll just lock to one branch of kernel/uboot for all K3 boards, I'll switch sources to that once it happens but should be ok for now.

Let me know if this looks good and can be merged or anything else is needed.
