# effects by failing to set up some hardware I/O registers in

# which prevented proper chip initialization and muted SCI1 output.

#  This section makes the target dependent options file.

#  NDEBUG (C library)
#     if defined asserts do not generate code.  This is commonly used
#     as a command line option.
#
#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
#     do not pause between screens of output in the rtems tests
#
#  RTEMS_DEBUG (RTEMS)
#     If defined, debug checks in RTEMS and support library code are enabled.
#
#  STANDALONE_EVB
#     This switch compiles code to jump-start from FLASH, without a monitor
#
#  START_HW_INIT
#     This switch selects whether 'early_hw_init()' is called from
#     'start.S'; 'bsp_hw_init()' is always called from 'bspstart.c'
