Does the "sleep" command work, with correct timing, i. e. will "sleep 5" sleep for approx. 5 seconds?
Yes - however that is using udelay which does not seem connected to the timestamp which is incremented in the PIT handler.
Anyway... I figured one reason why the PIT was not causing the timestamp to interate - I had interrupts turned off. I had interrupts_enable commented out from my very first days of working on u-boot.
Now - when I turn the interrupts on and then - and only when - I enable the PIT - u-boot gets a ProgramCheck.
So - Just to check, I looked to see if there was an address for a handler in the Interrupt Vector Table for the PIT - and I did not find a valid address.
However to cross-check myself, I looked in the IVT for the ProgramCheck vector (I used the BDI to dump 0x700) there was not a valid address there and no code.
So the question now is what should the IVT look like, and at what addresses should there be either vectors or code?
Thanks

my enet port status shows - "100 MBit/sec, full duplex" so I think that is a-okay -
Still can't figure out why I'm not getting a timer interrupt
