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.
