Subject: [PATCH v2 2/3] ARM: OMAP2+: remove custom abort handler for t410
Date: Thu, 15 Oct 2015 12:32:21 +0200	[thread overview]
Message-ID: <1444905142-21500-3-git-send-email-l.stach@pengutronix.de> (raw)
In-Reply-To: <1444905142-21500-1-git-send-email-l.stach@pengutronix.de>

This is not needed anymore. Handling a potentially pending imprecise external
abort left behind by the bootloader is now done in a slightly safer way inside
the common ARM startup code.
