[U-Boot] mcf5445x watchdog support in U-Boot

[Liew Tsi Chung-R5AAHP]

Matt,

Yes. I am planning to enable watchdog in mcf5445x in u-boot. Need to
investigate more in booting linux and the transition to starting the
linux kernel of watchdog behavior to make sure it is not causing problem
to the linux kernel.

Best Regards,
TsiChung

Hi TsiChung et al,

I was wondering if there are plans to support and utilise the watchdog
in the mcf5445x devices within U-Boot?

I've ported a kernel driver from the bitshrine gpp
(http://www.bitshrine.org/gpp/linux-2.6.25-mcfv4e-watchdog.patch) so
that it hooks into my 54455 hw (Freescale EVB), however I'd like to
configure and enable the watchdog in U-Boot with the intention that once
Linux starts, the responsibility of kicking the watchdog resides with a
user space app -> driver.

Thoughts?

Much appreciated.
