Create PHY Lib for U-Boot
Extends the mii_dev structure to participate in a full-blown MDIO and PHY driver scheme. The mii_dev structure and miiphy calls are modified in such a way to allow the original mii command and miiphy infrastructure to work as before, but also to support a new set of APIs which allow (among other things) sharing of PHY driver code and 10G support The mii command will continue to support normal PHY management functions (Clause 22 of 802.3), but will not be changed to support 10G (Clause 45). The basic design is similar to PHY Lib from Linux, but simplified for U-Boot's network and driver infrastructure. We now have MDIO drivers and PHY drivers An MDIO driver provides: read write reset A PHY driver provides: (optionally): probe config - initial setup, starting of auto-negotiation startup - waiting for AN, and reading link state shutdown - any cleanup needed The ethernet drivers interact with the PHY Lib using these functions: phy_connect() phy_config() phy_startup() phy_shutdown() Each PHY driver can be configured separately, or all at once using config_phylib_all_drivers.h (added in the patch which adds the drivers) We also provide generic drivers for Clause 22 (10/100/1000), and Clause 45 (10G) PHYs. We also implement phy_reset(), and call it in phy_connect(). Because phy_reset() is essentially the same as miiphy_reset, but: a) must support 10G PHYs, and b) should use the phylib primitives, we implement miiphy_reset, using phy_reset(), but only when CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this way, we save on compile size, even if we don't manage to save code size.
