Hey, don't take that too hard. I'm actually in tge midst of an LFS build centered on the raspi4, with shaded of learning to write boot code as well, and you can bet I'm scouring everything you wrote. No one can ever learn anything if no one writes this type of stuff down. sometimes the network of knowledge and laying out the precise line of questions to answer is the best way of charting out and communicating info for learners. So thank you for writing this!
