Maybe all that stuff is just disabled.
there are signs of the ancestors of the chip being mobile SoC's, and it has a lot of power management stuff, and the ability to turn off large chunks of the chip to extend battery life
so expect a lot of things to be disabled until the proper code requests it to be enabled
ive had trouble getting hdmi to work because of that
Most confusing is why the heck are there breakpoints in the bootrom code "bkpt" instruction
where are you seeing that? might it instead just be data?
Less confusing I guess is how they write assembly lines with four instructions in one line - I guess they must be executed concurrently.
do you have an example of that? ive not heard of anything like that
