From: Fabio Estevam Date: Thu, 6 Oct 2016 00:11:17 +0000 (-0300) Subject: configs/mx6udoo: Add initial support X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8ec127d8d87f3aa373be94fde2849de4e793131c;p=buildroot.git 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.
