BCM63146 is a Broadcom B53 based DSL Broadband SoC. It is part of the
BCA (Broadband Carrier Access origin) chipset family so it's added under
ARCH_BCMBCA platform. This initial support includes a bare-bone
implementation and dts with CPU subsystem, memory and ARM PL011 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.

Should you create a mapping for the AXI bus portion at PA 0x81000000
just so it is already in place for when you might need it?
