I have not much knowledge about seL4, but the boot process of the RPi
(all versions) is rather special:

Thanks for the R-Pi summary!

Some layers may be difficult to prove but that

should not make it impossible to do good work.

Something along the lines...

If Given: uboot is trusted.

If Given: USB IO is trusted to devices ...UVW, XYZ.

The value of accepting some "Givens" is that other levels of

work can move forward on a very inexpensive platform.

As a student platform the R-Pi is interesting because

the student has a worthy (sufficiently interesting) platform to

abuse for less than the price of a modern text book. Pop out the memory

card reload it and start over. The students laptop has not crashed.

There is an old adage that to work on a car at home you

need to have a second car available to go and get parts. With the

R-Pi spare flash memory cards and USB memory give

that spare vehicle to go and get parts....

Have fun.
