From 49c98dc42b706897e802af12d16349ff65a9bd43 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Wed, 22 Jan 2014 21:06:32 -0800 Subject: snow: Rename snow to daisy. The name snow goes by in many places in chromeos is daisy. Snow is technically a variant of daisy and should really be called daisy_snow, but for historical reasons the daisy board with no variant was used instead. To make it easier to work with within chromeos, this change renames the snow board to daisy.
