The old image names (`rpi-hwup-image` and +`rpi-basic-image`) are deprecated. + +## WiFi firmware blobs + +Be aware that the WiFi firmwares for the supported boards are not provided by +`linux-firmware` but by a custom recipe which only packages the needed blobs +for these boards. This is because the upstream `linux-firmware` doesn't support +or has outdated files for the blobs we need. The recipe +`linux-firmware-raspbian` is based on a fork of `linux-firmware` which +includes everything we need in order to fully support the WiFi hardware. All +machines define `MACHINE_EXTRA_RRECOMMENDS` accordingly.
