Subject: [ 32/48] ARM: SAMSUNG: Fix for S3C2412 EBI memory mapping

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jose Miguel Goncalves <jose.goncalves@...v.pt>

commit 3dca938656c7b0ff6b0717a5dde0f5f45e592be5 upstream.

While upgrading the kernel on a S3C2412 based board I've noted
that it was impossible to boot the board with a 2.6.32 or upper
kernel. I've tracked down the problem to the EBI virtual memory
mapping that is in conflict with the IO mapping definition in
arch/arm/mach-s3c24xx/s3c2412.c.
