I checked openwrt now, and the driver I found there (target/linux/imx6/files-4.1/drivers/net/phy/gw16083.c) is a dumb phy driver and not using DSA and judging from a quick look not exposing any switch functionality. So without getting more documentation the switch isn't supportable in mainline Linux/Debian. If it's ok to configure the switch in the boot loader (assuming this is possible using RMII) and use it as is in Linux I'd volunteer to get you machine supported by Debian. Judging from the people I'm in contact with during my dayjob, I'd say even when I sign an NDA sharing the documents for the switch isn't possible. Still I'd suggest that you ask your Marvell contact, to increase awareness of the needs and wishes of the open source people at Marvell. > few days if I consider getting support for that one into the mainline > kernel manageable for me.
