pico-imx6ul: convert ethernet function to DM_ETH
- Remove pinmux definition from pico-imx6ul.c - Enable NET_RANDOM_ETHADDR for temporary solution, because micrel_ksz8xxx driver does not support DM_ETH yet, so cannot read MAC address directly. Before enable DM_ETH: Net: FEC [PRIME] After enable DM_ETH: Net: Warning: using random MAC address - ca:3f:43:8f:67:d4 eth1: ethernet@20b4000 Here is the test commands: => dhcp BOOTP broadcast 1 DHCP client bound to address 10.88.88.94 (139 ms) *** ERROR: `serverip' not set Cannot autoload with TFTPGET => ping 8.8.8.8 Using ethernet@20b4000 device host 8.8.8.8 is alive Signed-off-by: Wig Cheng <wig.cheng@technexion.com> Reviewed-by: Fabio Estevam <festevam@gmail.com>
