Prototype code that adds SMP support to EMEV2.

At this point only the most basic form of SMP operation
is supported. TWD and CPU Hotplug support is excluded.

Based on V1 of the Emma Mobile EV2 code. Needs to be
reworked to coexist with DT. Work in progress.

Hi Magnus,

I tried out this patch on top of the next branch of Rafael's
renesas tree (5658c94) plus V2 of your Emma Mobile EV2 code but
I am only seeing one CPU.  Do I need some other tweaks?

The list of patches I have applied is as follows:

mach-shmobile: Emma Mobile EV2 SMP prototype code
ARM: mach-types: Manually add KZM-A9-GT
mach-shmobile: KZM9D board prototype support
mach-shmobile: Emma Mobile EV2 SoC base support
serial8250-em: Add DT support
serial8250-em: clk_get() IS_ERR() error handling fix
serial8250-em: Emma Mobile UART driver V2
serial8250: Introduce serial8250_register_8250_port()
serial8250: Clean up default map and dl code
serial8250: Use dl_read()/dl_write() on RM9K
serial8250: Use dl_read()/dl_write() on Alchemy
serial8250: Add dl_read()/dl_write() callbacks
8250.c: less than 2400 baud fix.
serial/8250_pci: Clear FIFOs for Intel ME Serial Over Lan device on BI
tegra, serial8250: add ->handle_break() uart_port op
clocksource: em_sti: Add DT support
clocksource: em_sti: Emma Mobile STI driver V2
clockevents: Make clockevents_config() a global symbol


And yes, I did enable CONFIG_SMP :)
