[PATCH 6/9] ARM: Make a Kconfig option for shared BCM2835/BCM2836 code.

Eric Anholt eric at anholt.net
Tue Apr 21 11:09:53 PDT 2015 

The 2836 in the Raspberry Pi 2 is the same as the 2835 in terms of
peripherals, it's just the CPU implementation that has changed.  We
need a new ARCH_BCM2836 to handle the CPU change, so make a hidden
ARCH_BCM283X Kconfig option for the peripherals to depend on.
