While we generally attempt to get rid of board specific files and replace
them with device tree based descriptions, a lot of platforms have not
come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.
In Kirkwood, we are adding support for new boards with a combination of
DT and board file contents in multiple cases.
pxa/mmp and imx are extending support for existing board files but not
adding new ones.

This is EMEV2 DT support V3. The support is limited to

handled by "em-sti". Clocks and SMP are not supported.

Tie in the Emma Mobile GPIO driver "em-gio" to
support the GPIOs on Emma Mobile EV2.
A static IRQ range is used to allow boards to
hook up their platform devices to the GPIOs.
DT support is still on the TODO for the GPIO driver,
so only platform device support is included here.

This is V3 of Emma Mobile EV2 SMP support.
At this point only the most basic form of SMP operation
is supported. TWD and CPU Hotplug support is excluded.
Tied to both the Emma Mobile EV2 and the KZM9D board
due to the need to switch on board in platsmp.c and
the newly introduced need for static mappings.
The static mappings are needed to allow hardware
acces early during boot when SMP is initialized.
This early requirement forces us to also map in
the SMU registers.
