Subject: [PATCH] ARM: SAMSUNG: fix to support for missing cpu specific map_io
Date: Tue, 30 Jul 2013 13:27:57 +0900 [thread overview]
Message-ID: <190501ce8cdd$2abd6780$80383680$%kim@samsung.com> (raw)
Since commit 7ed76e08 (ARM: EXYNOS: Fix low level debug support)
map_io() is not needed for exynos5440 so need to fix to lookup
cpu which using map_io(). Without this, kernel boot log complains
'CPU EXYNOS5440 support not enabled' on exynos5440 and panic().
