From a4ce9a2c719b1f7536ada1c9fa8f1eb672b04897 Mon Sep 17 00:00:00 2001 From: Ivan De Cesaris Date: Tue, 12 Jan 2016 16:30:18 +0100 Subject: quark: add Intel Quark mcu D2000 support Add support for the Intel Quark mcu D2000 using the new quark_d2xx target. Changes to the lakemont part are needed for the D2000 core and backwards compatible with the X1000 one.
