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.
