Linux "firmware" isn't really firmware, it's software. That's not what we're up against here.
The firmware for the keyboard does indeed reside in an FROM chip that belongs to the keyboard and touchpad. It runs on a dedicated microcontroller. Here is the wiki entry (which doesn't really describe this well) https://wiki.pine64.org/wiki/Pinebook_Pro#Keyboard
I always admired the 6502. So much that I still use it a lot today. ARM processors are technically 6502-inspired.
This thread suggests that there are other PBPs with the same issue as yours.
