Historically PHY intialization was disabled on motionpro board. Then at some point PHY init was enabled and only comment message was left.
After looking once more at the history I've found that this problem was actually fixed by

MPC5XXX, Motion-PRO: Fix PHY initialization problem.
which uses RESET_PHY_R feature to fix PHY initialization late in the boot process. But with drivers that initialize PHYs not during boot process but on the first access (I believe mpc5xxx_fec is not the only example) this RESET_PHY_R feature is completely broken. What would be the correct way to fix this? Should we add reset_phy() call in every driver that uses 'lazy' PHY initialization?
