From 7b250f8be3b8c496796dcdc954c9e5959cefea2c Mon Sep 17 00:00:00 2001
From: Bob Feretich <bob.feretich@rafresearch.com>

Subject: [PATCH 01/16] OMAP3 Beagle Pin Mux initialization glitch fix
The below patch reverses the order of two segments in the board file.
Output pins need to have their values initialized, before they are
exposed to the logic outside the chip.
