Subject: [PATCH] ARM: cacheflush: Remove unused secure_flush_area API
Date: Sat, 20 Aug 2016 01:07:01 -0500	[thread overview]
Message-ID: <1471673221-19181-1-git-send-email-andy.gross@linaro.org> (raw)

This patch removes the unused secure_flush_area function.  The only
consumer of this function has moved to using the streaming DMA APIs.
