This function will do everything it needs to do to initialise the AC Link Controller.

short int AC97_Init(                
  volatile GPIO_REGS*v_pGPIOReg,
  BYTE DevId ); 
short int InitAcLink(                
  volatile GPIO_REGS*v_pGPIOReg,
  BYTE DevId ); 


Pointer to GPIO-Registers.

0, reserved for future use.

Return Values

If this function succeeds, the return value is SUCCESS.
If the function fails, the return value is FALSE.


This will configure the GPIO's of the XScale-Controller and perform a Cold-Reset on the AC97-Unit. Keep in mind that other drivers/programms that use the AC97-Link (e.g. Touch-driver) won't really appreciate a Cold-Reset! In most cases it is recommended to use AC97_Alloc instead.
