-bcm2709: Drop platform smp and timer init code
-
-irq-bcm2836 handles this through these functions:
-bcm2835_init_local_timer_frequency()
-bcm2836_arm_irqchip_smp_init()
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-bcm270x: Use watchdog for reboot/poweroff
-
-The watchdog driver already has support for reboot/poweroff.
-Make use of this and remove the code from the platform files.

-board_bcm2835: Remove coherent dma pool increase - API has gone
