From 80abc8165e658f4538ef2ab00ceba118e097dbfd Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sun, 3 Jun 2018 19:04:16 -0700 Subject: [PATCH] x86: cougarcanyon2: Update dts for SPI lock down It turns out that like Braswell, Intel FSP for IvyBridge requires SPI controller settings to be locked down, as the U-Boot ICH SPI driver fails with the following message on Cougar Canyon 2 board: "ICH SPI: Opcode 9f not found" Update the SPI node property to indicate this fact.
