X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e8f1546a88b4ade6a910c4a7958a774ee1b40023;p=u-boot.git mxc_fec: fix some erroneous PHY accesses. 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-4.2 toolchains. Now using proper defines for auto-negotiation register.
