>How does one learn how to do this?

It's not something you can learn in a fortnight. You first have to learn C and Assembly for the architecture you're using, then you need to study how different OSs on different hardware manage to make themselves boot and then you need to use this knowledge to study the SoC's documentation and implement the stuff there. If documentation were perfect maybe you'd only need to know how to program and simply follow the specification, but in these cases experience with a large number of cases is a must to navigate the environment.
