+Subject: [PATCH] ARM: bcm2835: Add Kconfig support for bcm2836
+
+This should be a complete port of bcm2835 functionality to bcm2836
+(Raspberry Pi 2).
+
+v2: Implement Arnd's feedback to not split to ARCH_BCM2836, and
+ instead use more conditionals in ARCH_BCM2835. Also reduce diff
+ between 2835 and 2836.
