So despite 11 Software updates, there has only been five firmware updates.
When we're talking about fuses odm_reserved has 256 bits to play with. Assuming that one bit is 1 fuse. Then they can do 256 firmware updates before they're in trouble.
Firmware is a pretty horribly misused term these days.
Not every update is a firmware update. But every update is a software update.
Firmware in this context is (most likely from what I can tell) 2nd stage bootloader that exists in EFI. It's pretty rarely updated. This is Package1 that they talk about here and http://switchbrew.org/index.php?title=System_Versions here. Even less if we're talking about firmware updates that burnt a fuse (bottom of this page http://switchbrew.org/index.php?title=Fuse_registers#FUSE_RE...)
