PATCH 2/2 ARM: shmobile: Temporarily use emev2_map_io() for SMP

From: Magnus Damm <[email protected]>

To run SMP together with DT we need to use emev2_map_io on EMEV2. This due to some early requirements for ioremap().

Instead of blindly applying this I believe we should spend time looking into why the common ARM ioremap() code dies early instead of behaving sanely and returning NULL.

So for now I prefer not to merge this. Anyone wanting to use and/or develop code for KZM9D can instead make use of the code in board-kzm9d.c.
