This depends on the quality and level of datail of the other documen-
tation you have. I  prefer  to  be  able  to  verify  this  form  the
schematics  (which  usually  is  more  up-to-date than all text docs,
too).

Maybe, maybe not. I don't know your board.  Does  your  documentation
explain the use of all port pins, clock routing, how to reset the PHY
etc.?

It depends...
