SAMA5D3 Xplained: SPL broken after panic added to /lib/time.c:94

Hi again,

FYI: As a small test I commented out the change you mentioned but got the
same mistake. Begs to wonder if it is
 related to the issue at hand.

Going back to
http://u-boot.10912.n7.nabble.com/PATCH-v2-time-Fix-get-ticks-being-non-monotonic-td426172.html

Sean Anderson asks:

"So nothing here is probed, but additionally nothing has UCLASS_TIMER.
What do you expect the timer device to be?"

Is the timer missing for SAMA5D3 board? I cannot find it in /drivers/timer,
other than mchp-pit64b-timer.c, which doesn't
seem to be used ins this particular board as far as I could tell.

Any thoughts on how to fix this? Anything I can do to help?

Cheers
