From 11da9d23fe323ce452fcd04a10a0ddf78eaa63ea Mon Sep 17 00:00:00 2001 From: Amaury Pouly Date: Wed, 12 Jun 2013 19:46:04 +0200 Subject: imxtools: move hwemul to its own directory The hwemul is only partly imx specific: the stub is stmp specific but could be ported to other targets, the computer side and the protocol are mostly stmp independent (or should be).
