Revision 1.1, Fri Aug 8 13:18:16 2008 UTC (15 years, 9 months ago) by nbrk
Branch: MAIN
CVS Tags: HEAD

Start implementing basic hardware support for CATS, based on new autoconfiguration
mechanism. This effectively uses bus_space to abstract children of parents.
Some info about these drivers:
hostio is a host memory-mapped i/o - one and only child of 'root';
footbridge is just a proxy for now;
fuart is a DC21285 UART driver which fills uart_attach_args and attaches
com, which is machine independent driver;

This all is not finished yet (just quick hacks), but commit it so i could work at home.
