ARM: add basic support for the Broadcom BCM2835 SoC This SoC is used in the Raspberry Pi, for example. For more details, see: http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf. Initial support is enough to boot to a serial console, execute a minimal set of U-Boot commands, download data over a serial port, and boot a Linux kernel. No storage or network drivers are implemented. GPIO driver originally by Vikram Narayanan <vikram186@gmail.com> with many fixes from myself. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

/*
bcm2836 SoC support (used in Raspberry Pi 2 model B) 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.
