1.2.5: Low Power Mode

The macro SPARC_HAS_LOW_POWER_MODE is set to one to indicate that this CPU model has a low power mode. If low power is enabled, then there must be CPU model specific implementation of the IDLE task in cpukit/score/cpu/sparc/cpu.c. The low power mode IDLE task should be of the form:

while ( TRUE ) {
  enter low power mode
}

The code required to enter low power mode is CPU model specific.
