17# This board support package works with several different versions of
18# MC68360 systems.  See the conditional-compile tests in startup/init68360.c
19# for examples.
20#
21# Decisions made at compile time include:
22#       - If the CPU is a member of the 68040 family, the BSP is
23#         compiled for a generic 68040/68360 system as described
24#         in Chapter 9 of the MC68360 User's Manual.  This version
25#         can be used with the Arnewsh SBC360 card.
26#       - If the preprocessor symbol M68360_ATLAS_HSB is defined,
27#         the BSP is compiled for an Atlas HSB card.
28#       - If the preprocessor symbol M68360_IMD_PGH is defined,
29#         the BSP is compiled for an IMD PGH360 card.
30#       - Otherwise, the BSP is compiled for a generic 68360 system
31#         as described in Chapter 9 of the MC68360 User's Manual.  This
32#         version works with the Atlas ACE360 card.

276Porting
277-------
278This board support package is written for a 68360 system similar to that
279described in chapter 9 of the Motorola MC68360 Quad Integrated Communication
280Processor Users' Manual.  The salient features of this hardware are:
281
282        25 MHz external clock
283        DRAM address multiplexing provided by 68360
284        8-bit 180nsec PROM to CS0*
285        4 MBytes of 60 nsec parity DRAM (1Mx36) to RAS1*/CAS1*
286        Console serial port on SMC1
287        Ethernet interface on SCC1
288
289The board support package has been tested with:
290        A home-built 68360 board
291        An ACE360A and an HSB board produced by:
292                Atlas Computer Equipment
293                703 Colina Lane
294                Santa Barbara, CA 93103
295        A 68040/68360 board (SBC360) produced by:
296                Arnewsh Inc.
297                P.O. Box 270352
298                Fort Collins, CO 80527-0352
299        A custom 68360 board (PGH360) produced by IMD
