The firmware download you point to has a license which does not allow
for redistribution of the firmware, therefore we cannot add it to
Ubuntu's linux-firmware package. I checked upstream linux-firmware but
the firmware isn't present there.
I'm marking this confirmed, but unfortunately we can't do anything
unless Broadcom provides a license which allows us to redistribute the
firmware.
** Changed in: linux-firmware (Ubuntu)
