# # $Id$ # # # This package requires a version of GCC that supports the `-mcpu32' option. # # # Please send any comments, improvements, or bug reports to: # W. Eric Norum # Saskatchewan Accelerator Laboratory # 107 North Road # University of Saskatchewan # Saskatoon, Saskatchewan, CANADA # S7N 5C6 # eric@skatter.usask.ca # # # 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. # - 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. # # Decisions to be made a link-edit time are: # - The size of the memory allocator heap. The default value is # 64 kbytes. If the network package is used the heap # should be at least 256 kbytes. If your network is large, or # busy, the heap should be even larger. # To choose a heap size of 256 kbytes, # CFLAGS_LD += -Wl,--defsym -Wl,HeapSize=0x40000 BSP NAME: gen68360 or gen68360_040 BOARD: Generic 68360 as described in Motorola MC68360 User's Manual BOARD: Atlas Computer Equipment Inc.
