[U-Boot-Users] [PATCH] Add support for the TK885D baseboard from TELE-DATA
Guennadi Liakhovetski
lg at denx.de
Thu Jan 10 17:59:07 CET 2008
The TK885D board uses a TQM885D module from TQ, this port adds an
own configuration file and adds a last_stage_init() method to
configure the two PHYs, depending on the phy_auto_nego environment
variable.
