description:
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!
