Macros
#define	LINKER_SYMBOL(sym)
#define	CPU_Get_timebase_low(_value)
#define	rtems_bsp_delay(_microseconds)
#define	rtems_bsp_delay_in_bus_cycles(_cycles)
#define	PPC_Set_decrementer(_clicks)
#define	PPC_Get_decrementer(_clicks)
#define	PPC_STRINGOF(x)
	Preprocessor magic for stringification of x.
#define	PPC_SPECIAL_PURPOSE_REGISTER(spr, val)
	Returns the value of the Special Purpose Register with number spr.
#define	PPC_SET_SPECIAL_PURPOSE_REGISTER(spr, val)
	Sets the Special Purpose Register with number spr to the value in val.
#define	PPC_SET_SPECIAL_PURPOSE_REGISTER_BITS(spr, bits)
	Sets in the Special Purpose Register with number spr all bits which are set in bits.
#define	PPC_SET_SPECIAL_PURPOSE_REGISTER_BITS_MASKED(spr, bits, mask)

	Sets the Thread Management Register with number tmr to the value in val.
#define	PPC_DEVICE_CONTROL_REGISTER(dcr)
	Returns the value of the Device Control Register with number dcr.
#define	PPC_SET_DEVICE_CONTROL_REGISTER(dcr, val)
	Sets the Device Control Register with number dcr to the value in val.
#define	PPC_SET_DEVICE_CONTROL_REGISTER_BITS(dcr, bits)
	Sets in the Device Control Register with number dcr all bits which are set in bits.
#define	PPC_SET_DEVICE_CONTROL_REGISTER_BITS_MASKED(dcr, bits, mask)
	Sets in the Device Control Register with number dcr all bits which are set in bits. The previous register value will be masked with mask.
#define	PPC_CLEAR_DEVICE_CONTROL_REGISTER_BITS(dcr, bits)
	Clears in the Device Control Register with number dcr all bits which are set in bits.
