Really?  It's listed under the help (taken from out docker images):
$ /opt/qemu/bin/qemu-system-riscv64 --help
...
Debug/Expert options:
-fw_cfg [name=]<name>,file=<file>
                add named fw_cfg entry with contents from file
-fw_cfg [name=]<name>,string=<str>
                add named fw_cfg entry with contents from string
