# This board support package works with several different versions of
# MC68360 systems. The choice of hardware is made at the final link-edit
# phase by setting the Makefile CLAGS_LD definition appropriately.
#
# 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.
# - 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.
#
# 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
