In this change, our first SOC is an armv7 platform called 47622. The initial support includes a bare-bone implementation and dts with ARM PL011 uart. The SOC-specific code resides in arch/arm/mach-bcmbca/ and board related code is in board/broadcom/bcmba. The u-boot image can be loaded from flash or network to the entry point address in the memory and boot from there.
