Implemented in a + "natural" way by invoking the PHY reset and initialization code + only once after power on vs. each time the interface is brought up. + * Add some limited support for low-speed devices to SL811 USB controller (at least "usb reset" now passes successfully and "usb info" displays correct information) diff --git a/cpu/mpc5xxx/fec.c b/cpu/mpc5xxx/fec.c index 1df394a..5355a81 100644 --- a/cpu/mpc5xxx/fec.c +++ b/cpu/mpc5xxx/fec.c @@ -238,7 +238,6 @@ static int mpc5xxx_fec_init(struct eth_device *dev, bd_t * bis) DECLARE_GLOBAL_DATA_PTR; mpc5xxx_fec_priv *fec = (mpc5xxx_fec_priv *)dev->priv; struct mpc5xxx_sdma *sdma = (struct mpc5xxx_sdma *)MPC5XXX_SDMA; - const uint8 phyAddr = CONFIG_PHY_ADDR; /* Only one PHY */ #if (DEBUG & 0x1) printf ("mpc5xxx_fec_init...
