From 811acf923d8a0052f22b50306d9362d7e0f8e108 Mon Sep 17 00:00:00 2001 From: Igor Grinberg Date: Mon, 22 Apr 2013 01:06:53 +0000 Subject: cm-t35: move cm-t35 to live in compulab directory Currently the cm-t35 support code lives under board/cm_t35 directory. Some of the code can be shared with other/future CompuLab boards, so move the cm-t35 to live under board/compulab/cm_t35 directory.
