- Selects fec_mxc.c to be compiled into u-boot.
+ Selects fec_mxc.c to be compiled into u-boot. Can read out the

CONFIG_FEC_MXC_PHYADDR

+Reading the ethaddr from the SoC eFuses:
+if CONFIG_FEC_MXC is defined and the U-Boot environment does not contain the
+ethaddr variable, then its value gets read from the corresponding eFuses in
+the SoC. See the README files of the specific SoC for details.
