From 5f0a88a1aabb2b332e2fa01598cc24e708552771 Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Mon, 25 Mar 2019 11:30:17 -0700 Subject: [PATCH] ARM: dts: vf610-zii-cfu1: Disable NOR flash/SPI controller Only a certain number of CFU1's come with NOR flash populated. Disable it by default to avoid trying to probe NOR flash on devices that don't have it. Devices that do have it can rely on the bootloader to enable this node.
