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

# which prevented proper chip initialization and muted SCI1 output.

# 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'
