linux-firmware/source.sh

# This is the source.sh script. It is executed by BPM in a temporary directory when compiling a source package
# BPM Expects the source code to be extracted into the automatically created 'source' directory which can be accessed using $BPM_SOURCE
# BPM Expects the output files to be present in the automatically created 'output' directory which can be accessed using $BPM_OUTPUT
