This patch serie adds support for the TS-4600 boards rev A and B. These
boards, manufactured by Technologic Systems, are based on an i.MX28.

This serie include the support for the watchdog which could be enable
at Linux boot time depending on the bootloader.

The watchdog and few peripherals are implemented in a FPGA, and can
only be access using a custom GPIOs bit-banged bus which is called the
NBUS by Technologic Systems.
A driver for this bus is also included and used by the watchdog.
