Hi Heiko
I'm struggling somewhat with getting our mpc8309-derived board converted
to DM_ETH. I just get
Net: No ethernet found.
where I used to get
Net: UEC0, UEC1, UEC2
and there's no errors or other diagnostics printed (I've also tried
adding #define DEBUG 1 to the .c files under drivers/net/qe/, still
nothing).
The board already used OF_CONTROL, so I've tried extending the
device-tree based partly on you changes for the km boards, partly from
our linux device tree - the two mostly agree:

I only define two ethernet devices in DT above - the third (middle one)
is used for ethercat and irrelevant in U-Boot.
I have not set CONFIG_PINCTRL{,_QE} since our qe_iop_conf_tab is just
const qe_iop_conf_t qe_iop_conf_tab[] = {
{0, 0, 0, 0, QE_IOP_TAB_END}, /* END of table */
};
so config_qe_ioports() should be a no-op.
Can you see something obviously wrong with the above, and/or do you have
some hints as for what I can do to figure out why the drivers apparently
do not pick up the devices from DT? 'dm drivers' does list
ucc_geth 033 eth <none>
qe_uec_mdio 051 mdio <none>
Thanks,
Rasmus
