From 914627fe1c575112cd2aa14ab83cfa249e6810d6 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 23 Dec 2014 20:01:44 -0700 Subject: [PATCH] ARM: rpi: consolidate board rev error checking Create a fake model table entry with default values, so we can error check the board rev value once when querying it from the firmware, rather than error-checking for invalid board rev values every time the model table is used.
