>From [1]:
This kernel option allow exporting of the QEMU firmware configuration (fw_cfg)
file entries via sysfs. Entries are found under /sys/firmware/fw_cfg when this
option is enabled and loaded.
Enable the suboption to allow the qemu_fw_cfg device to be initialized via the
kernel command line or using a module parameter.
