After digging into the serial port problem I am seeing, I think the code
dies in the fcomcnattach() routine, on line 671 of footbridge_com.c when
it tries to call the bus_space_map macro. I am new to this stuff, but it
appears to me that bus_space_map simply maps in the footbridges registers
to fcomconsioh, which is a bus_space_handle_t. I wasn't real clear on
how the macro worked, but I think I traced it down to fcomcons_bs_map()
in footbridge_com_io.c. All this function appears to do is the actual
assignment above. Mark, have you seen anything like this on the ebsa285
or CATS board?
