This series is a rework of the previously posted patch: - [RFC PATCH v2 08/11] powerpc: gamecube/wii: early debugging using usbgecko
It tries to implement the ideas suggested by Benjamin Herrenschmidt regarding the use of a fixmap entry to provide a valid I/O mapping immediately after MMU_init runs and MMU is definitively enabled.
