6# This package requires a version of GCC that has been modified
7# to support the `-m68360' argument.  I have submitted the required changes
8# to the GCC maintainers.  Should they choose to use a different argument
9# (-mcpu32 perhaps) this board support package will have to be changed.

252Porting
253-------
254This board support package is written for a 68360 system similar to that
255described in chapter 9 of the Motorola MC68360 Quad Integrated Communication
256Processor Users' Manual.  The salient details of this hardware are:
257
258        25 MHz external clock
259        DRAM address multiplexing provided by 68360
260        8-bit 180nsec PROM to CS0*
261        4 MBytes of 60 nsec parity DRAM (1Mx36) to RAS1*/CAS1*
262        Console serial port on SMC1
263
264The board support package has been tested with a home-built board and with an
265ACE360A board produced by:
266        Atlas Computer Equipment
267        703 Colina Lane
268        Santa Barbara, CA 93103
