wdk d9c3de97f0 Add bus_dma hooks for ISA Bus. 
ISA bus option doesn't support DMA on the Magnum 3000 series, but other
models such as the M/120 do support it.

wdk 8cd59636b4 Support for ISA expansion slot in Mips 3230 
The ISA Bus on this machine doesn't support DMA, and all interrupt lines
are wire-OR'ed together.   Mileage may vary if sharing interrupts.

Tested cards:
     com:  8250 and 16550 UART's (8 bit)
     ec:   3com Etherlink II (8 bit)
     we:   SMC 8013 Ethernet (16 bit) [work in progress]
             Probes, ARP in both directions works, sends clean packets,
             tcpdump show correct packets on receive, NDP for IPv6 works,
	     netstat -s shows nothing strange.. but doesn't talk TCP/IP!
