From 8ec127d8d87f3aa373be94fde2849de4e793131c Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 5 Oct 2016 21:11:17 -0300 Subject: [PATCH] configs/mx6udoo: Add initial support Add the initial support for mx6q/dl udoo boards. For information about these boards, please visit: http://www.udoo.org/ In linux.fragment we disable USB support for now because kernel 4.8 hangs on udoo board. This is been addressed by Peter Chen's kernel patch series that provides a standard way to reset a USB hub. When such series hit mainline, then we can bump the kernel and remove linux.fragment.
