With this change driver will benefit from existing phylib and thus custom phy functionality implemented in the driver will go away: * Instantiation of the driver is now much shorter - 2 parameters instead of 4. * Simplified phy management/functoinality in driver is replaced with rich functionality of phylib. * Support of custom phy initialization is now done with existing "board_phy_config". Note that after this change some previously used config options (driver-specific PHY configuration) will be obsolete and they are simply substituted with similar options of phylib. For example: * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled by default. * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise automatically the first discovered on MDIO bus phy will be used I believe there's no need now in "doc/README.designware_eth" because user only needs to instantiate the driver with "designware_initialize" whose prototype exists in "include/netdev.h".
