Freescale i.MX7 support added

[Ryo Shimizu <ryo%nerv.org@localhost>]

Hi all

I have commited about adding support Freescale i.MX7 processor
and Atmark Techno Armadillo-IoT G3 board.
 - http://armadillo.atmark-techno.com/armadillo-iot-g3
   (only available in Japanese)

UART/Ethernet/USB/SDHC/RTC/GPIO/WDOG and MULTIPROCESSOR works.


And now, i.MX7Dual processor has two Cortex-A7 cores and one Cortex-M4 core.
An M4 core is slower than A7, and more importantly, it has no MMU.
I don't know how/what to use M4 core on netbsd.
Does anyone have a nice idea/framework?  or for blinking LED? ;-)
