This can be used if we do not want to use an EEPROM for the configuration.

What is managed switch? Which chip it supports? Why it is sitting here and not in generic folder?
In this case, the switch is a Marvell 88E52xxx (don't remember the exact model) that is connected to the GE port of the Kirkwood and that gets configured by the Kirkwood through a MDIO link, using indirect addressing.
We do not have the pretention to write a generic driver for such switches/addressing, but we need this functionnality on some boards, that's why we have kept it in our own folder and not in a generic driver folder.
I will add the above precisions to the commit message for an optional v3 of the "updates for the Keymile Marvell boards" series so that this is more clear.
