From 04bfbf50950df6ef78aa354698b226928a4024bc Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Wed, 22 Jan 2014 20:50:27 -0800 Subject: pit: Rename pit to peach_pit. The name pit goes by in many places in chromeos is peach_pit, where peach is the base name and pit is the name of this particular variant. To make it easier to work with within chromeos and to make the board names a little less ambiguous, this change renames the pit board to peach_pit, and from Pit to Peach Pit.
