-/*
- Boot the CPU.
-
- Occurs in 3 phases for a 68302.
-
- Phase 1.
-
- Called as soon as able after reset. The BAR has been programed, and
- a small stack exists in the DPRAM. All interrupts are masked, and
- the processor is running in supervisor mode. No other hardware or
- chip selects are active.
-
- This phase programs the chip select registers, the parallel ports
- are set into default configurations, and basic registers cleared or
- reset. The leds are programmed to show the end of phase 1.
-
- Phase 2.
-
- This is a piece of code which is copied to DPRAM and executed. It
- should not do any more thann is currently present. The return to ROM
- is managed by modifing the return address. Again leds show the status.
-
- Phase 3.
-
- This code executes with a valid C environment. That is the data
- section has been intialised and the bss section set to 0. This phase
- performs any special card initialisation and then calls boot card.
