This patch enables BRIDGE and DP83848_PHY as kernel modules for AM57xx,
AM437x and AM335x SoCs. BRIDGE is to support STP/RSTP Switch mode using
PRU-ICSS which got recently merged and DP83848 PHY driver to support
TI TLK10X PHY.

Bridge does not look suitable for defconfig or I still miss something
here. Is it a dependency for some driver?
In case you wonder: this is not a distro config. It is not meant to be
working for your customers...
Best regards,
Krzysztof

The PRU-ICSS sub-system available in TI AM57x/AM437x/AM335x SOCs is capable of
operating as HW offloaded L2 switch (STP/RSTP) with 2 PRU ports, by using Linux
switchdev.
The proposed changes are required to enable "bridge" config to get the support
for Linux switchdev, hardware offload features, and STP support to get a fully
functional L2 offloaded switch.
Thanks and Regards,
Parvathi.
