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.

BCM68360 is a variant within the BCM6856 chip family. Now that BCM6856 is supported under CONFIG_ARCH_BCMBCA and CONFIG_BCM6856, remove the original ARCH_BCM68360 support and migrate its configuration and dts settings. This includes: - Remove the bcm968360bg board folder. It is replaced by the generic bcmbca board folder. - Merge the 68360.dtsi setting to the new 6856.dtsi file. Update board dts with the new compatible string. - Merge broadcom_bcm968360bg.h setting to the new bcm96856.h file.

Changes in v2: - Bring Philippe Reynes copyright tag from 68360 dts to 6856 dts
