Hello, I've tried to adapt the PHY detection code to allow for dynamic runtime configuration (with fallback to search for the 2nd MAC PHY on the 1st MAC's MII bus), as well as selectable static PHY configuration through Kconfig (e.g. for supporting PHYs w/o MII connection) e.g. for a MIPS BOSPORUS board, one would set something like through Kconfig (haven't bothered yet, to autoselect this when MIPS_BOSPORUS is defined): CONFIG_MIPS_AU1X00_ENET=y CONFIG_MIPS_AU1X00_ENET_STATIC_PHY_CONFIG=y CONFIG_MIPS_AU1X00_ENET_ETH0_PHY_ADDR=5 CONFIG_MIPS_AU1X00_ENET_ETH1_PHY_ON_MAC0=y CONFIG_MIPS_AU1X00_ENET_ETH1_PHY_ADDR=-1 the default dynamic runtime PHY search behaviour is now to find the lowest phy_addr containing a living PHY (which is not already claimed by another MAC) on the MAC's current MII bus, and if not found, try again on the first MAC's MII bus; and if that also fails eth initialization fails for the given MAC; ...well, if anyone has the time and hardware, testing would be greatly welcomed :-) alas, this patch is rather big and I'd like to split it into smaller pieces, but imho it's an 'all or nothing' thing to convert to the PHY lib... :-/ Kconfig | 31 + au1000_eth.c | 1494 ++++++++++------------------------------------------------- au1000_eth.h | 132 ----- 3 files changed, 310 insertions(+), 1347 deletions(-) regards, hvr
