-# This package requires a version of GCC that supports the `-mcpu32' option.

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

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