I miss the point - which is the difference with ar8035_config() in
drivers/net/phy/atheros.c and why cnnot you reuse it ? Can we avoid to
duplicate the code ?

This is also copied from sabresd. Can we factorize in some way ?

I do not understand why setup_display() should be called at this point.
Generally, board_early_init_f() is called to setup iomux for peripherals
needed before relocation, as uart, letting the rest of the setup in
board_init(). Why do you need here ?
