Houston, we have a problem here.
Please see current arch/arm/boards/raspberry-pi/rpi.c:

/* See comments in mbox.h for data source */
static const struct {
	const char *name;
	bool has_onboard_eth;
	void (*init)(void);
} models[] = {
	RPI_MODEL(0, "Unknown model", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_I2C0_2, "Model B (no P5)", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_I2C0_3, "Model B (no P5)", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_I2C1_4, "Model B", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_I2C1_5, "Model B", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_I2C1_6, "Model B", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_A_7, "Model A", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_A_8, "Model A", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_A_9, "Model A", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_REV2_d, "Model B rev2", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_REV2_e, "Model B rev2", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_REV2_f, "Model B rev2", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_B_PLUS, "Model B+", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_CM, "Compute Module", NULL),
	RPI_MODEL(BCM2835_BOARD_REV_A_PLUS, "Model A+", NULL),
};

All inits are NULLs!

Have we any chance to run rpi_add_led()?
