Pixel C firmware downloader and archiver

This script fetches and archives the necessary firmware for the Pixel C.

To use, simply exec:

./get_firmware.sh

The result is two archives:

• firmware_all.tar.gz
• firmware_brcm_extra_only.tar.gz

The first archive contains all the firmware needed to bring up the onboard hardware. The second archive contains only the parts not present out of box in the linux-firmware repository/packages.

If your distro provides a linux-firmware package, it is recommended to install that and then use the firmware_brcm_extra_only.tar.gz archive to supply the rest of the files, otherwise you can use the firmware_all.tar.gz archive. The primary reason to use linux-firmware as whole is for potential peripherals needing proprietary blobs.

If you are sure you won't be needing any of those and want something minimal that does not take up extra space, feel free to use firmware_all.tar.gz.
