Hi all,
the problems boiled down to two things:
- full MII and non-shared MII-management interface is not
currently supported for MCF5445x
- when a PHY returns id 0x0, matching for this ID results in
a lock-up in mcfmii.c
considering PHY ID 0x0 as broken anyways, I could get my board
to run with both ethernet interfaces with the patch below. As this
is not yet thoroughly tested and my tree is too much out of sync
at the moment, I do not provide a proper patch for now, but maybe
this already helps somebody else in case he runs into the same
problems.
Regards,
Wolfgang
