This adds support for the CPU watchdog found on Marvell Armada 37xx SoCs. There are 4 counters which can be set as CPU watchdog counters. This driver uses the second counter (ID 1, counting from 0) (Marvell's Linux also uses second counter by default). In the future it could be adapted to use other counters, with definition in the device tree. Signed-off-by: Marek Behun <marek.behun@nic.cz> Signed-off-by: Stefan Roese <sr@denx.de>

This option enables U-Boot watchdog support where U-Boot is using
|
|
watchdog_reset function to service watchdog device in U-Boot. Enable
|
|
this option if you want to service enabled watchdog by U-Boot. Disable
|
|
this option if you want U-Boot to start watchdog but never service it.

Enable driver model for watchdog timer. At the moment the API
|

is very simple and only supports four operations:
|
|
start, restart, stop and reset (expire immediately).

What exactly happens when the timer expires is up to a particular

device/driver.

The watchdog timer is stopped when initialized. It performs reset, either

full SoC reset or CPU or just some peripherals, based on the flags.

It currently does not support Boot Flash Addressing Mode Detection or

Second Boot.
