From 592578a1dd1be0c940e36f769acdd3cc6651a7a1 Mon Sep 17 00:00:00 2001 From: Richard Retanubun Date: Wed, 8 Apr 2009 11:51:27 +1000 Subject: [PATCH] m68knommu: Fixed GPIO pin initialization for CONFIG_M5271 FEC. This processor only have one FEC and its MDIO pins are located at a different offset than the code used for the current CONFIG_M527x. Tesed on M5271EVB eval platform. Without this patch the FEC driver will report no PHY attached if the bootloader does not pre-initialize the PAR_FECI2C GPIO register.
