Public bug reported:
The size of the pi-kernel snap for UC20 is 254Mbytes (compressed) and
794Mbytes (uncompressed).
569Mbyte of this is caused by FW
140Mbyte -> Netronome SmartNIC
Removing unreferenced FW and/or reducing number of drivers & their FW
has exponential reduction of disk space usage.
Additionally, downloaded image will be smaller; and storing 3x kernel
snaps for upgrades will be smaller.
Even more, snap seeding will be faster, so boot time will be faster.
So it will be a nice gain in multiple aspects: download image, boot
image, upgrade image, reboot image, start using image.
