[U-Boot] cpsw not working with slave2 port defined only

Hi,

I have custom am33xx board with phy connected to slave2 port. I
copy'n'paste cpsw setup from /board/BuR/common/common.c but I'm using
only slave2 port (RMII mode) so my cpsw_slave_data looks like:

static struct cpsw_slave_data cpsw_slaves[] = {
{
                 .slave_reg_ofs  = 0x308,
                 .sliver_reg_ofs = 0xdc0,
                 .phy_addr       = 4,
},
};

with this configuration cpsw driver can detect link but it cannot
establish any communication (tested with dhcp command). When I add to
cpsw_slaves dummy slave1 port definition (with e.g. phy_addr = 0) it
start working.

mdio bus is working fine (tested with mdio list + mdio read). Pinmux
is good as it works with dummy slave1 config. Any ideas what I'm doing
wrong or why only slave2 port cannot be used? I grep whole source code
but all boards using cpsw use slave1 only or slave1/slave2
configurations. Many thanks.

BR,

marek
