Subject: [PATCH] ARM: optimize for FA526 if toolchain supports it
Date: Mon, 23 Apr 2012 14:31:53 +0200 [thread overview]
Message-ID: <1335184313-27573-1-git-send-email-florian@openwrt.org> (raw)
Currently, when we are targetting a Farady FA526-based system
the toolchain will use the arm9tdmi mtune option of gcc, gcc > 4.6
supports the FA526 CPU, and allow us to optimize for it.
