From ede69f0d627bb7546bff4e6b640e86b641d2ca15 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 19 Jul 2016 17:39:05 -0500 Subject: mainboard/google/reef: reverse the memory config bits I mistakenly assumed the order of the bits matched how one would assign values as they wrote them msb .. lsb. However, the gpio lib doesn't do that. Correct the order so that values are read out correctly.
