From 3af52a1a6d71ac3d78e0dec56da2fd8eb07a91d1 Mon Sep 17 00:00:00 2001
From: Adam Ford aford173@gmail.com Date: Wed, 4 Nov 2015 17:13:15 -0600 Subject: [PATCH] omap3_logic: Cleanup and remove redundant defines make bootz easier
Some unnecesary includes still exist from the initial conversion to ti_omap3_common.h
Add some boot scripts to allow for other boot options and unify some environmental variable names with other omap3 devices.
