The newly implemented fwnode_mdbiobus_register turned out to be
problematic - in case the fwnode_/of_/acpi_mdio are built as
modules, a dependency cycle can be observed during the depmod phase of
modules_install, eg.:
depmod: ERROR: Cycle detected: fwnode_mdio -> of_mdio -> fwnode_mdio
depmod: ERROR: Found 2 modules in dependency cycles!
OR:
depmod: ERROR: Cycle detected: acpi_mdio -> fwnode_mdio -> acpi_mdio
depmod: ERROR: Found 2 modules in dependency cycles!
A possible solution could be to rework fwnode_mdiobus_register,
so that to merge the contents of acpi_mdiobus_register and
of_mdiobus_register. However feasible, such change would
be very intrusive and affect huge amount of the of_mdiobus_register
users.
Since there are currently 2 users of ACPI and MDIO
(xgmac_mdio and mvmdio), withdraw the fwnode_mdbiobus_register
and roll back to a simple 'if' condition in affected drivers.

If you have a network (Ethernet) card belonging to this class, say Y.

Note that the answer to this question doesn't directly affect the

kernel: saying N will just cause the configurator to skip all

the questions about Freescale devices. If you say Y, you will be

The MPC5200's FEC can connect to the Ethernet either with
|
|
an external MII PHY chip or 10 Mbps 7-wire interface
|
|
(Motorola? industry standard).
|
|
If your board uses an external PHY connected to FEC, enable this.
|
|
If not sure, enable.
|
|
If compiled as module, it will be called fec_mpc52xx_phy.
