Source code IS a documentation for "real hard coders". But for rest of us it is not....
Is there any documentation of piCore bootloader, builder and installation internals?
...probably there is not, but i have to ask first. I have bad memory, so I have to make docs for myself anyway, and of course I will publish docs for community, if valued.
For that, I have to ask lot of very stupid questions for developers, is that ok?
