[PATCH v3 5/7] [ARM]: U8500 integrate to ARM architecture

[srinidhi kasagar]

From: srinidhi kasagar <srinidhi.kasagar@stericsson.com>

This hooks the U8500 support into the ARM kbuild
system. This integration also enables SMP and its
helper funtions for u8500 platform

[PATCH v3 6/7] [ARM]: adds AB4500 as pl022 device

[srinidhi kasagar]

From: srinidhi kasagar <srinidhi.kasagar@stericsson.com>

This adds AB4500 device support for the
mop500 board. AB4500 connects to U8500
on the SSP/SPI bus.

to use SMP with
config HAS_SMP
	bool
