I thought about writing a generic firmware module using the new
FreeBSD API which reads firmware files from a certain directory
using fp_open().
However, it seems that available firmware images need to be announced
with firmware_register() to make them available, so I would need some
sort of opendir() in kernel to scan the firmware directory and
register the available files with firmware_register().
Alternatively we could adjust subr_firmware.c to trigger a file read
attempt in case the requested image has not yet been registered.
