Considering that the pins aren't relocatable (ie, the GPIO numbers
never change), I've got no problem having the GPIO reset logic added
to arch/powerpc/platforms/52xx and hard coding

something that you've found happens to work on
These patches reimplement the reset fuction in the ac97 to use gpio pins
instead of using the mpc5200 ac97 reset functionality in the psc. This
avoids a problem in which attached ac97 devices go into test mode appear
unresponsive.
These patches were tested on a pcm030 baseboard and on custom
