From 690094e2d7d9cfe5eb4edb478fd79e5d133c6b4b Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 15 Sep 2013 14:11:50 -0700 Subject: altos: Move micropeak sources around This sticks the micropeak sources in appropriate directories, rather than in the micropeak product directory so that they can be shared with future micropeak-style products.
