Hi Greg,
If /sys/firmware is the right place, that is where I will put it.
Are the rules for /sys/firmware documented? Documentation/sysfs-rules.txt does not mention /sys/firmware. It seems to indicate that /sys/class should only contain symlinks:
There are currently three places for classification of devices: /sys/block, /sys/class and /sys/bus. It is planned that these will not contain any device directories themselves, but only flat lists of symlinks pointing to the unified /sys/devices tree.
