[PATCH 1/2] powerpc: mpc85xx_mds: Select PHYLIB only if NETDEVICES is enabled

[Andrey Smirnov]

PHYLIB depends on NETDEVICES, so to avoid unmet dependencies warning
from Kconfig it needs to be selected conditionally.

Also add checks if PHYLIB is built-in to avoid undefined references to
PHYLIB's symbols.

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

[Andrey Smirnov]

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.
