After the patch from Markus Klotzbuecher (Bugfix in FEC initialisation from 12. July 2006) FEC2 on the TQM885D board is not working after boot. Only after a 'mii info' command FEC2 could be used. The reason for this is that the PHY for FEC2 is not recognized properly.
This patch changes the TQM885D configuration from automatic PHY detection to predefined (fix) PHY types. With this FEC2 (and FEC + SCC) works without problems.
