Return to sacpcic_jornada.c CVS log

Up to [local] / sys / arch / jornada / dev

Sync up my latest modifications related to OpenBSD/jornada.
At this point PCMCIA is not done (this is primary goal since it's only
expansion bus for SA-1110) but some other chip subsystems rather work.
One of most recent problems sit in ported NetBSD pcic driver. It cause memory
abort passing odd addr to bus_space_write_2 (APB transactions are word-wide,
but I try to emulate 2-bytes accesses in bus_space_map for sa1111).
Other problematic/untested areas: sacic, saic. UART driver is a stub and not
really useful.
But even with this problems I have overdone my plans with this porting effort.
