BCM6858 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_BCM6858 chip config and CONFIG_ARCH_BCMBCA platform config. This initial support includes a bare-bone implementation and the original dts is updated with the one from linux next git repository. 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.
