Subject: [U-Boot] [PATCH V2 8/9] configs: ti_omap3_common: Enable workaround for ARM errata 454179, 430973, 621766
Date: Tue, 24 Feb 2015 16:52:13 -0600	[thread overview]
Message-ID: <1424818334-29398-9-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1424818334-29398-1-git-send-email-nm@ti.com>

Enable the OMAP3 specific errata code for 454179, 430973, 621766
and while at it, remove legacy non-revision checked errata logic.
