The bcm2835 and bcm2836 are essentially identical, except: - The CPU is an ARM1176 v.s. a quad-core Cortex-A7. - The physical address of many IO controllers has moved. Rather than introducing a whole new bcm2836 value for $(SOC) or $(ARCH), update the existing bcm2835 code to handle the minor differences, and plumb it into the ARMv7 CPU architecture.
