BeagleBone Black

Has anyone attempted to use Grub with the BeagleBone?

Mender docs state:

By default, Mender uses GRUB to boot, and this is the recommended bootloader to use, even on platforms that ordinarily use U-Boot. However, U-Boot can be used in cases where using GRUB is not possible or unsuccessful.

So I thought it might be a good idea to try to use Grub with Mender on the BeagleBone but I am trying to figure out how to get started with that.
