General init of the chip hardware I would do in other modules. some exceptions, to be done at the very beginning of startup 1) if you have a watchdog, it is recommended to disable it in startup and reenable it in main, The code in startup and the 'secret' module it calls before main is entered can be quite lenghty 2) if you have a XRAM cnfiguration register and the default does not match your hardware you need to set it here. 3) DO NOT reset port pins to avoid them being high after reset here, the duration of reset can be disastrous if you rely on a port pin being reset as default.
There are other exceptions, the above is what I can think of off the bat.

Good points. Some initialization has to be done immediately, and is a good candidate for startup.a51.
