I see why this would need a separate defconfig, but why do you also
need a new dts file ?

And if you need just a minor dts tweak, please just include the
existing dts file and make the tweak, rather then writing a
whole new dts file.

Also have you submitted the dts file to the upstream kernel ?

Regards,

Hans

There is no need to set these 3 options, they are the default.

Likewise for these 3 options, they are on by default too.

OTOH you do like want to do:

CONFIG_USB_EHCI_HCD=y

So that the usb ports will work in u-boot.
