[U-Boot] [PATCH v4 0/3] x530: Enable watchdog

[Chris Packham]

We've seen some issues with the x530 under extreme conditions where the
DDR gets into a bad state. Generally this results in an application
crash followed by a lock-up in u-boot.

Enabling the watchdog prevents the lock up and will let the DDR training
have another go. Sometimes this recovers but even a reboot loop is
better than a complete lockup.

Changes in v4:
- use DIV_ROUND_UP to avoid setting the timeout to 0.

Changes in v3:
- new
- specify timeout in milliseconds

Changes in v2:
- update commit message

Chris Packham (3):
  watchdog: orion_wdt: support SPL usage
  watchdog: orion_wdt: take timeout value in ms
  arm: mvebu: x530: Enable watchdog in SPL and U-Boot
