From 7cd67018dd7f754c66cf08a76397bbee254b32aa Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pali=20Roh=C3=A1r?= Date: Mon, 1 Aug 2022 23:58:42 +0200 Subject: [PATCH] arm: mvebu: turris_omnia: Remove hardcoded spi-nor device tree path MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Linux kernel DTS files renamed spi-nor@0 node to flash@0 which effectively broke U-Boot to boot new Linux kernel versions correctly. So remove hardcoded spi-nor device tree path from Turris Omnia board code and replace it by searching for mtd node by compatible string.
