21 | # This board support package works with several different versions of |
---|
22 | # MC68360 systems. See the conditional-compile tests in startup/init68360.c |
---|
23 | # for examples. |
---|
24 | # |
---|
25 | # Decisions made at compile time include: |
---|
26 | # - If the CPU is a member of the 68040 family, the BSP is |
---|
27 | # compiled for a generic 68040/68360 system as described |
---|
28 | # in Chapter 9 of the MC68360 User's Manual. This version |
---|
29 | # can be used with the Arnewsh SBC360 card. |
---|
30 | # - If the preprocessor symbol M68360_ATLAS_HSB is defined, |
---|
31 | # the BSP is compiled for an Atlas HSB card. |
---|
32 | # - Otherwise, the BSP is compiled for a generic 68360 system |
---|
33 | # as described in Chapter 9 of the MC68360 User's Manual. This |
---|
34 | # version works with the Atlas ACE360 card. |
---|
35 | # |
---|
36 | # Decisions to be made a link-edit time are: |
---|
37 | # - The size of the memory allocator heap. The default value is |
---|
38 | # 64 kbytes. If the network package is used the heap |
---|
39 | # should be at least 256 kbytes. If your network is large, or |
---|
40 | # busy, the heap should be even larger. |
---|
41 | # To choose a heap size of 256 kbytes, |
---|
42 | # CFLAGS_LD += -Wl,--defsym -Wl,HeapSize=0x40000 |

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