#
#  A Generic m68k config.arch that can be included by other platforms
#  to reduce the number of places that need to be edited when something
#  common changes.  If you include this file you may provide:
#
#  CPUFLAGS            - cpu specific flags to pass to the compiler
#  VENDOR_CFLAGS       - vendor specific flags to pass to the compiler
#  DISABLE_XIP         - set this to 1 to disable XIP code
#  DISABLE_SHARED_LIBS - set this to 1 to disable shared libraries
#  DISABLE_MOVE_RODATA - set this to 1 to disable moving rodata to text
#  LOPT                - library optimisation flags
#  UOPT                - user optimisation flags
