- cmdline include quiet: console is among slooowest devices you have! (maybe instead convince kernel to disable console when some GPIO isn't pulled high, so you can have debug möde?)
- already using pre-measured bogomips value at cmdline, right?
- maybe one additional layer of abstraction would help on the "strangeness" that is old RPi: If you, instead of Linux directly, only load the much slimmer uboot romboot,that's fewer bytes that a freaking GPU management controller has to fetch;

@manawyrm and then the much faster (main) CPU takes over, executes the small uboot SPL, which then initializes just enough things to be able to jump to linux.
