[U-Boot] [PATCH] net/designware - switch driver to phylib usage

[Alexey Brodkin]

Completely forgot to mention that there's a prerequisite
(http://patchwork.ozlabs.org/patch/309319/):
======
[PATCH] net: execute "miiphy_init" if CONFIG_PHYLIB defined
======

This makes sure that phylib will be correctly initialized even if
there's no explicit mention of either entry in board configuration:
 * CONFIG_MII
 * CONFIG_CMD_MII

Even though all existing boards do have CONFIG_MII set still it's good
to have all missing parts in place.
