Functions
void	multicore_reset_core1 (void)
	Reset core 1.
void	multicore_launch_core1 (void(*entry)(void))
	Run code on core 1.
void	multicore_launch_core1_with_stack (void(*entry)(void), uint32_t *stack_bottom, size_t stack_size_bytes)
	Launch code on core 1 with stack.
void	multicore_launch_core1_raw (void(*entry)(void), uint32_t *sp, uint32_t vector_table)
	Launch code on core 1 with no stack protection.
static bool	multicore_fifo_rvalid (void)
	Check the read FIFO to see if there is data available (sent by the other core).
static bool	multicore_fifo_wready (void)
	Check the write FIFO to see if it has space for more data.
void	multicore_fifo_push_blocking (uint32_t data)
	Push data on to the write FIFO (data to the other core).
static void	multicore_fifo_push_blocking_inline (uint32_t data)
	Push data on to the write FIFO (data to the other core).
bool	multicore_fifo_push_timeout_us (uint32_t data, uint64_t timeout_us)
	Push data on to the write FIFO (data to the other core) with timeout.
uint32_t	multicore_fifo_pop_blocking (void)
	Pop data from the read FIFO (data from the other core).
static uint32_t	multicore_fifo_pop_blocking_inline (void)
	Pop data from the read FIFO (data from the other core).
bool	multicore_fifo_pop_timeout_us (uint64_t timeout_us, uint32_t *out)

static void	multicore_fifo_drain (void)
	Discard any data in the read FIFO.
static void	multicore_fifo_clear_irq (void)
	Clear FIFO interrupt.
static uint32_t	multicore_fifo_get_status (void)
	Get FIFO statuses.
void	multicore_lockout_victim_init (void)
	Initialize the current core such that it can be a "victim" of lockout (i.e. forced to pause in a known state by the other core).
void	multicore_lockout_victim_deinit (void)
	Stop the current core being able to be a "victim" of lockout (i.e. forced to pause in a known state by the other core).
bool	multicore_lockout_victim_is_initialized (uint core_num)
	Determine if multicore_lockout_victim_init() has been called on the specified core.
void	multicore_lockout_start_blocking (void)
	Request the other core to pause in a known state and wait for it to do so.
bool	multicore_lockout_start_timeout_us (uint64_t timeout_us)
	Request the other core to pause in a known state and wait up to a time limit for it to do so.
void	multicore_lockout_end_blocking (void)
	Release the other core from a locked out state.
bool	multicore_lockout_end_timeout_us (uint64_t timeout_us)
	Release the other core from a locked out state.
