Matthieu! Thanks so much for your help! I'll try it out and let you know how it goes.
Is there a certain flavor of `sysutils/u-boot` that I need to install? I see on OpenPorts.se that there are 2 flavors: 1. 'aarch64', and 2. 'arm'. Not sure if that's referring to the architecture of the compiling machine or the machine we're compiling for. Anyways, thanks so much for the help. Have a great day sir!
