> @Johnnynator not sure if I want to drop the linux-firmware dependency. nothing on the board itself needs it.

Most of the other `-base` package do not depend on `linux-firmware` or only a specific subpackage, so I don't think there is an expectation for it being installed by a boards `-base` package, so do not add it, if the board doesn't need it.
