+SUMMARY = "Linux kernel firmware files from Raspbian distribution"
+DESCRIPTION = "Updated firmware files for RaspberryPi hardware. \
+RPi-Distro obtains these directly from Cypress; they are not submitted \
+to linux-firmware for general use."
+HOMEPAGE = "https://github.com/RPi-Distro/firmware-nonfree"
+SECTION = "kernel"
+
+# In maintained upstream linux-firmware:
+# * brcmfmac43430-sdio falls under LICENCE.cypress
+# * brcmfmac43455-sdio falls under LICENCE.broadcom_bcm43xx
+#
+# It is likely[^1] that both of these should be under LICENCE.cypress.
+# Further, at this time the text of LICENCE.broadcom_bcm43xx is the same
+# in linux-firmware and RPi-Distro/firmware-nonfree, but this may
+# change.
+#
+# Rather than make assumptions about what's supposed to be what, we'll
+# use the license implied by the source of these files, named to avoid
+# conflicts with linux-firmware.
