From 5d24ceab4eaf0dd7825c5a06dc6f264c0a59660c Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Wed, 3 Oct 2012 11:34:18 +0000 Subject: [PATCH] MIPS: BCM47xx: read out full board data Read out the full board data independently of the sprom version. Now we also get the full boardflags and so on if sromrev is not set and our code would assume a rev 1 device. When a nvram option is not set because it is not there this is no problem.
