--- Comment #21 from Vincent Milum Jr <freebsd@darkain.com> ---
Just as an update to this, I've been doing quite a bit more research on
building multi-board compatible u-boot configs.

It looks as though the settings we're using for CONFIG_ENV_FAT_DEVICE_AND_PART
is based on legacy config params for u-boot, that are no longer needed.

Modern u-boot will now auto-detect the proper volume on its own. This is now
working great for me, one less thing I need to split between different board
configs in my lab!

CONFIG_ENV_FAT_DEVICE_AND_PART=""

This value should now be an empty string for Aarch64 targets. u-boot is smart
enough to figure it out dynamically on its own rather than requiring a custom
config up-front. We should entirely remove the statically listed value now.
