Install the Firmware

Make your work directory and clone the official firmware repo into it. Copy the appropriate boot firmware files to the sysroot, along with the video acceleration binaries. If you want to use the wireless networking function, you need the bcrm firmware as well.

root # mkdir -p ${KERNEL_WORK}
root # git clone --depth 1 git://github.com/raspberrypi/firmware/ ${KERNEL_WORK}/firmware
root # cp ${KERNEL_WORK}/firmware/boot/{bootcode.bin,fixup*.dat,start*.elf} ${SYSROOT}/boot
root # cp -r ${KERNEL_WORK}/firmware/hardfp/opt ${SYSROOT}
root # git clone --depth 1 https://github.com/RPi-Distro/firmware-nonfree ${KERNEL_WORK}/firmware-nonfree
root # git --git-dir=${KERNEL_WORK}/firmware-nonfree/.git --work-tree=${KERNEL_WORK}/firmware-nonfree pull origin
root # mkdir -p ${SYSROOT}/lib/firmware/brcm
root # cp -r ${KERNEL_WORK}/firmware-nonfree/brcm/brcmfmac43430-sdio.{bin,txt} ${SYSROOT}/lib/firmware/brcm
