[PATCH 2/2] powerpc: e8248e: Select PHYLIB only if NETDEVICES is enabled

From: Andrey Smirnov
Date: Tue Jul 26 2016 - 00:30:34 EST


Select PHYLIB only if NETDEVICES is enabled and MDIO_BITBANG only if
PHYLIB is present to avoid warnings from Kconfig.

To prevent undefined references during linking register MDIO driver only
if CONFIG_MDIO_BITBANG is enabled.
