   I guess the question is, are these out-of-tree smartphone SoC drivers written like that, or are they just one big driver for all the devices that upstream didn't have drivers for

     @wolf480pl @muvlon They're custom ARM CPUs with different capabilities and often completely different ways to boot them and bring them online. They can't be supported with a common/shared framework in the kernel.
     
     aarch64 is an example of a common ARM CPU standard that can be supported and they'll all support UEFI instead of special binary blobs
     
     I'm not an expert in this area but I've read into it a bunch and talked to devs about it, especially FreeBSD kernel devs. I'm sure others can chime in with more precise details

     Someone explained to me how the Raspberry Pi boots but my brain keeps rejecting it.

     @resuna @muvlon @wolf480pl I believe the GPU is involved and that's when my brain said "no, this is not worth knowing about"

     It's like the SoC equivalent of the Coleco Adam where the power supply for the computer was in the printer.
