I got pretty confused - which MAC is used on the Colibri VF50 on the Iris carrier? According to the Colibri VFxx datasheet and the Iris Carier datasheet, the pins of MAC0 are used (along with Micrel PHY). The pins are 189/187/195/193 etc. However in DTS the fec0 is disabled (DTS based on vf-colibri-eval-v3.dtsi).
During boot I see also:
[ 1.596528] fec 400d1000.ethernet
eth0: Freescale FEC PHY driver [Micrel
… so it is MAC1, not MAC0.
Which one is it at the end? Am I missing something or datasheets mixed up the numbers (0/1)?
