+From 58ecb60d53d43e8d584708722a2cf851ba88f9e1 Mon Sep 17 00:00:00 2001
+From: Linus Walleij <linus.walleij@linaro.org>
+Date: Thu, 11 Oct 2018 19:53:40 +0200
+Subject: [PATCH 05/18] mtd: physmap_of: Move custom initialization
+
+In order to be able to assign custom complex mappings
+to the physmap_of plugin for Gemini, move the initialization
+so that the simple map is initialized before we enter the
+platform-specific functions so the latter can override
+them.
+
