From c5fb04cc96c1812eb09a3b0f3672f4a00d76730c Mon Sep 17 00:00:00 2001 From: Thor Thayer Date: Mon, 11 Apr 2016 12:01:34 -0500 Subject: ARM: socfpga: Initialize Arria10 OCRAM ECC on startup Initialize ECC for Arria10 On-Chip RAM on machine startup. The OCRAM memory must be initialized before data is stored in memory otherwise the ECC will fail on reads. The previous check-in 2364d423a7b3 ("ARM: socfpga: Enable Arria10 OCRAM ECC on startup") added the OCRAM enable and initialization code but was not called on startup.
