From be5f3623204e15cb8a95a6d381ae6eb074ba46b5 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Fri, 18 Nov 2011 00:17:46 +0000 Subject: [PATCH] MIPS: ath79: Store the SoC revision in a global variable Knowing the exact revision of the SoC is required to make runtime decisions in various code paths. We have determined the SoC revision already, so we only need to store that in a global variable.
