should i really add this link to commit description?

i tried to leave dts compatible with linux dts and only added relevant parts, but switch-driver works differently in 
uboot so i dropped it in v2 (and plan to disable gmac in v3). have not yet tried ethernet. only bootup, usb and sata 
(mmc is same as evb).

as u-boot doesn't care iodomain till jonas patches i have used evb devicetree/defconfig, but if this gets activated 
and users do not recognize this they brick their board. So imho this should be added before iodomain gets enabled in 
evb defconfig.
