0002 ========
0003
0004 This package requires a version of GCC that supports the `-mcpu32` option.

0007
0008 This board support package works with several different versions of
0009 MC68360 systems. See the conditional-compile tests in startup/init68360.c
0010 for examples.
0011
0012 Decisions made at compile time include:
0013 - If the CPU is a member of the 68040 family, the BSP is
0014 compiled for a generic 68040/68360 system as described
0015 in Chapter 9 of the MC68360 User's Manual. This version
0016 can be used with the Arnewsh SBC360 card.
0017 - If the preprocessor symbol M68360_ATLAS_HSB is defined,
0018 the BSP is compiled for an Atlas HSB card.
0019 - If the preprocessor symbol M68360_IMD_PGH is defined,
0020 the BSP is compiled for an IMD PGH360 card.
0021 - Otherwise, the BSP is compiled for a generic 68360 system
0022 as described in Chapter 9 of the MC68360 User's Manual. This
0023 version works with the Atlas ACE360 card.

0274 -------
0275 This board support package is written for a 68360 system similar to that
0276 described in chapter 9 of the Motorola MC68360 Quad Integrated Communication
0277 Processor Users' Manual. The salient features of this hardware are:
0278
0279 25 MHz external clock
0280 DRAM address multiplexing provided by 68360
0281 8-bit 180nsec PROM to CS0*
0282 4 MBytes of 60 nsec parity DRAM (1Mx36) to RAS1*/CAS1*
0283 Console serial port on SMC1
0284 Ethernet interface on SCC1
0285
0286 The board support package has been tested with:
0287 A home-built 68360 board
0288 An ACE360A and an HSB board produced by:
0289 Atlas Computer Equipment
0290 703 Colina Lane
0291 Santa Barbara, CA 93103
0292 A 68040/68360 board (SBC360) produced by:
0293 Arnewsh Inc.
0294 P.O. Box 270352
0295 Fort Collins, CO 80527-0352
0296 A custom 68360 board (PGH360) produced by IMD
