I don't know at all.  And actually, I am more concerned that other registers
might be unreliable within the first microsecond after reset is de-asserted.

Are you guaranteeing that the documented PoR time is achieved before reading registers?

Yes, that is the idea, why I added the udelay directly after releasing the reset,
thus simply delaying the execution of the stmmac_hw_init function, and not directly
where the synopsys_id register is accessed.


Thanks
Bernd.
