BCM6856 is a Broadcom B53 based PON Gateway SoC. It is part of the BCA (Broadband Carrier Access origin) chipset family. Like other Broadband SoC, this patch adds it under CONFIG_BCM6856 chip config and CONFIG_ARCH_BCMBCA platform config. This initial support includes a bare-bone implementation and dts with CPU subsystem, memory and Broadcom uart. This SoC is supported in the linux-next git repository so the dts and dtsi files are copied from linux. The u-boot image can be loaded from flash or network to the entry point address in the memory and boot from there to the console.
