Where in the LS1012a-Freedom code is GPIO_RST_B controlled?

Our custom board design diverged from the LS1012a Freedom reference board in that we have an eMMC on SDHC controller 1 and therefore need to configure pin 75 to SDHC1_VSEL (rather than GPIO1[23]). We moved this signal to pin 122 (GPIO1[13]).

Pin 122 is not connected to anything on the Freedom board. The LS1012A RM says the bit 424-425 RCW value of "11" is "GPIO1[13], RESET_REQ_B". We did not change RESET_REQ_B so I left this unchanged. Note: the CodeWarrior IDE RCW configuration tool indicates that "11" is reserved (and not what it how it mux's these pins.

 

However, I am unable to locate where in the code GPIO1[23] is utilized to reset the Ethernet PHYs and our PHYs appear to be held in reset.

Can anyone point me to the code I need to study/modify?

 

Thanks!
