From 58ecb60d53d43e8d584708722a2cf851ba88f9e1 Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>

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.
