Raspberry Pi hardware requires firmware that supersedes or is not present in the standard linux-firmware distribution. These files are maintained in the RPi-Distro project on github. Several attempts have been made to reconcile conflicts between what's in linux-firmware and what the hardware needs. The existing approach is functional but not maintainable since it combines material from three repositories into a single package that claims to be linux-firmware. Remove the appends that change the content of linux-firmware for rpi hardware. Add two new recipes that follow the RPi-Distro repositories: * firmware-nonfree which forked from linux-firmware and replaces content is provided as linux-firmware-rpidistro; * bluez-firmware which forked from (very old) bluez and adds content is provided as bluez-firmware-rpidistro. The packages are named to make clear that these come from RPi-Distro, rather than generic sources. Licensing attempts to record the state of licensing as documented in RPi-Distro.

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.
