/***************************************************************************
rs6000_type7xxx.cpp - IBM RS/6000 PowerPC based MicroChannel systems
Skeleton by R. Belmont
Type 7009: PPC 601 @ 80 MHz, serial console, SCSI, 3-digit 7-segment display,
4 MCA slots, Ethernet, and a 2.88MB floppy with an unknown controller
The NetBSD boot log for a Type 7011 indicates the integrated SCSI is
an NCR 53C720 appearing as an MCA board with the ID word 0x8fba.
The "I/O planar" appears as an MCA board with the ID word 0x8f98 and
it contains two NS16550A UARTs and an unknown Ethernet chip.
