Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.This feature is useful when your board uses different mii buses for differentphys and all (or a part) of these buses are implemented via bit-banging mode.The driver requires that the following macros should be defined into the boardconfiguration file:CONFIG_BITBANGMII - Enable the miiphybb driverCONFIG_BITBANGMII_MULTI - Enable the multi bus supportIf the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needsto define at least the following macros:MII_INIT - Generic code to enable the MII bus (optional)MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)MDIO_ACTIVE - Activate the MDIO pin as out pinMDIO_TRISTATE - Activate the MDIO pin as input/tristate pinMDIO_READ - Read the MDIO pinMDIO(v) - Write v on the MDIO pinMDC_DECLARE - Declaration needed to access to the MDC pin (optional)MDC(v) - Write v on the MDC pinThe previous macros make the driver compatible with the previous version(that didn't support the multi-bus).When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fillthe bb_miiphy_buses[] array with a record for each required bus and declarethe bb_miiphy_buses_num variable with the number of mii buses.The record (struct bb_miiphy_bus) has the following fields/callbacks (seemiiphy.h for details):char name[] - The symbolic name that must be equal to the MII bus registered nameint (*init)() - Initialization function called at startup time (just before the Ethernet initialization)int (*mdio_active)() - Activate the MDIO pin as outputint (*mdio_tristate)() - Activate the MDIO pin as input/tristate pinint (*set_mdio)() - Write the MDIO pinint (*get_mdio)() - Read the MDIO pinint (*set_mdc)() - Write the MDC pinint (*delay)() - Delay functionvoid *priv - Private data used by board specific codeThe board code will look like:struct bb_miiphy_bus bb_miiphy_buses[] = { { .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... }, { .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... }, ...int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) / sizeof(bb_miiphy_buses[0]);Signed-off-by: Luigi 'Comio' Mantellini Signed-off-by: Ben Warren List of files: /rk3399_rockchip-uboot/doc/README.bitbangMII
