Sorry if this is a dumb question. I'm having the hardest time finding the name of android's analogue of the Unified Extensible Firmware Interface.
Maybe they are specific to each manufacturer? I am specifically looking for the one used with Samsung galaxy phones.
Is there an opensource specification for interfacing with android phone hardware, similar to how UEFI and BIOS works?
The closest thing I have found is Replicant OS. The description says "Replicant is a fully free Android distribution running on several devices". If it can run on many devices would that mean its using the same firmware 'interface' across many devices?
