This patch adds basic support for the Broadcom BCM63138 DSL SoC which is
using a dual-core Cortex A9 system. Add the very minimum required code
boot Linux on this SoC.
Due to the two specific register address spaces located at 0x8000_0000
and 0xfffe_0000, we need to setup a specific iotable descriptor for
those to be remapped at the expected virtual addresses.
Finally, the PL310 cache controller requires a bit of tweaking before
handing its initialization over l2x0_of_init(), this is also taken care
of to make sure that its size is properly configured.

Low-level debugging using the Broadcom Kona UART only makes sense on the
ARCH_BCM_MOBILE platform and would otherwise prevent ARCH_BCM_63XX from
picking up the right UART implementation by default.

Broadcom BCM63xx DSL SoCs have a different UART implementation for which
we need specially crafted low-level debug assembly code to support. Add
support for this using the standard definitions provided in
include/linux/serial_bcm63xx.h (shared with their MIPS counterparts).

peripherals:
- Cortex A9 CPU
- ARM GIC
- PL310 Level-2 cache controller
- ARM TWD & Global timers
- ARM TWD watchdog
- legacy MIPS bus (UBUS)

Why do you use "63xx" for the generic name, when the specific
part you are defining here is 63138? I would have expected
"63xxx".

The product line has a mix of 4-digit and 5-digit part numbers. The
drivers for onchip peripherals all used "bcm63xx":
$ find drivers/ | grep 63xx

That's too bad. I would suggest that one or the other be used
consistently, apparently "63xx" (not 63xxx) would be it.

Gentle ping, patch 2 should not be too controversial and could
probably be queued for a next 3.14-rc pull request?

Thanks for merging patch 2, can I borrow some of your bandwidth to
review the remainder of the patches?
