Subject: [PATCH] EDAC, altera: SoCFPGA EDAC should not look for ECC_CORR_EN
Date: Wed, 14 Oct 2015 18:14:16 -0500	[thread overview]
Message-ID: <1444864456-21778-1-git-send-email-dinguyen@opensource.altera.com> (raw)

From: Dinh Nguyen <dinguyen@opensource.altera.com>

The bootloader may or may not enable the ECC_CORR_EN bit. By not enabling
ECC_CORR_EN, when error happens, it is the user's responsibility to perform
a full SDRAM scrub.

Remove the check for ECC_CORR_EN.
