Subject: [U-Boot] [RFC PATCH 3/4] OMAP3+: Use -march=armv7-a and thereby enable Thumb-2
Date: Mon, 6 Feb 2012 17:07:27 +0530 [thread overview]
Message-ID: <1328528248-20872-4-git-send-email-aneesh@ti.com> (raw)
In-Reply-To: <1328528248-20872-1-git-send-email-aneesh@ti.com>
Enable -march=armv7-a for OMAP3+ platforms. This in turn
results in Thumb-2 code generated for these platforms if
CONFIG_SYS_THUMB_BUILD is enabled.
