# Issue:  New firmware as of Fedora 34/RHEL 9 uses xz-compressed firmware files
# Unfortunately, the Rpi loader for wifi (brcm/broadcom) specifies files directly, and doesn't support the .xz files
# This is a simple hacky script to extract xz files in the brcm firmware directory and extract them, so they can be loaded properly
