From 926870478d1fd5e8cf6a38716c9cf1ae845435e1 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Wed, 28 Jun 2017 15:40:32 +0200 Subject: [PATCH] arm64: zynqmp: Fix SVD mask for getting chip ID Mask should start from the first bit - using 0xe is just wrong. 3bits are used that's why 0x7 mask is correct. This patch is fixing silicon ID code detection. Previous behavior was that bit0 was completely ignored. Issue was found on 2eg chip detection.
