This is the initial support for Broadcom's ARM-based 47622 SOC.
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/<soc> 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.
