This patch fixes erroneous access to the ethernet PHY which broke the driver. 1. Selector field in the auto-negotiation register must be 0x00001 for using 802.3, not 0x00000 which is reseved. 2. Access to the PHY address specified by CONFIG_FEC_MXC_PHYADDR, not 0x0 fixed address.
This has been tested in i.MX27 Litekit board and eldk-2.0 toolchains.
