I forgot to Cc you but I'm currently reworking the physmap driver to merge the physmap_of logic in it [1]. I'll probably ask you to rebase this patchset on top of mtd/next once [1] is applied. Sorry for the inconvenience.

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.
