Last change on this file since ecc4594 was e2d79559, checked in by Joel Sherrill <joel.sherrill@…>, on Apr 9, 1997 at 2:05:50 PM

Added ka9q tcpip stack and network driver for the gen68360. This effort
was done based on the 3.6.0 release and had to be autoconf'ed locally.
It is turned on is the bsp enables it and it is not explicitly disabled
via the configure option --disable-tcpip. As many warnings as possible
were removed locally after the code was merged. Only the gen68360
and mvme136 bsps were compiled this way.

The ka9q port and network driver were submitted by Eric Norum
(eric@…).

The network demo programs are not included in the tree at this point.

6# This package works best with a version of GCC that has been modified
7# to support the `-mcpu32' argument.  I have submitted the required
8# changes to the GCC maintainers.

23# This board support package works with several different versions of
24# MC68360 systems.  The choice of hardware is made at the final link-edit
25# phase by setting the Makefile LDFLAGS definition appropriately.
26#
27# Decisions to be made a link-edit time include:
28#       - The version of hardware on which the application is to run.
29#         This is selected by defining the MC68360HardwareType variable.
30#         Supported values are:
31#                       MC68360HardwareTypeMotorolaGeneric (default)
32#                       MC68360HardwareTypeAtlasHSB
33#         To select the Atlas Computer Equipment HSB,
34#               --defsym MC68360HardwareType=MC68360HardwareTypeAtlasHSB
35#
36#       - The amount of dynamic RAM in the system.  This value applies
37#         only to hardware versions which support different sizes of RAM.
38#         The default value is 4 Mbytes.  To specify 16 Mbytes of memory,
39#               --defsym RamSize=0x1000000
40#
41#       - The size of the memory allocator heap.  The default value is
42#         64 kbytes.  If the KA9Q network package is used the heap
43#         should be at least 256 kbytes.  If your network is large, or
44#         busy, the heap should be even larger.
45#         To choose a heap size of 256 kbytes,
46#               --defsym HeapSize=0x40000
47#

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