1.1
log
@Add a new m68k port oriented towards home-brew m68k machines.  Flattened
Device Tree is used to make it simple to integrate support for new systems
with minimal added glue code.

The first supported system is the thorpej-designed Phaethon 1, a 68010-based
system with a custom MMU, 8MB of on-board RAM, 2 16650-type serial ports,
a PCF8584 I2C controller, DS3231/3232 real-time clock, ATA disk interface,
I/O controller with system timer and interrupt controller, and a "not quite
VME" expansion bus for memory and peripheral expansion.

I'm working with other 68k-home-brewers to get support for their systems
integrated.  So, more to come.
