This is a quick fix to stablize what
currently users encountered bootup stall.
This fix is found under board boot trials.
No logical code can be explained why it
fails the SDRAM calibration but applying.
A bit follow up on this patch.
When user turned on the watchdog on
u-boot-xxxx.dts while having the original
setup triggers the SDRAM calibration fail.
While users those do not turn on the watchdog.
w/o this patch could be fine and not sure
what is the proper way to link the dts and
watchdog driver accordingly.
Always included the watchdog driver should
not be harm (correct me if not).
What the dts does can either initialize it or not.
What w/o the driver and dts setting to "okay"
does break things.
So Tom I am not sure based on your experiences.
Always attach driver and leave dts to do the job?
Device Tree is representation of the hardware. Is the watchdog present
in hardware? Yes? Then status = "okay".
Ideally, the board shouldn't fail if watchdog is enabled in DT but not
the driver (and vice-versa).
Do you know what the actual issue is? Why does it fail when watchdog is
enabled in DT but not the driver?
