From mboxrd@z Thu Jan 1 00:00:00 1970 From: jlu@pengutronix.de (Jan Luebbe) Date: Fri, 30 Jun 2017 16:50:58 +0200 Subject: [PATCH 0/8] EDAC drivers for Armada XP L2 and DDR Message-ID: <20170630145106.29820-1-jlu@pengutronix.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This series adds drivers for the L2 cache and DDR RAM ECC functionality as found on the MV78230/MV78x60 SoCs. I've tested these changes with the MV78460 (on a custom board with a DDR3 ECC DIMM). Also contained in this series are an additional debugfs wrapper and devm_ helpers for edac_mc_/edac_device_ allocation and registration, which make error handing and cleanup simpler. Compared to the previous RFC series, the following changes have been made: - Integrated Chris' patches for parity and ECC configuration via DT - Merged the DDR RAM and L2 cache drivers (as requested by Borislav, analogous to fsl_ddr_edac.c and mpc85xx_edac.c) - Added myself to MAINTAINERS (requested by Borislav) - L2 cache: Track the msg size and use snprintf (review comment by Chris) - L2 cache: Split error injection from the check function (review comment by Chris) - DDR RAM: Allow 16 bit width in addition to 32 and 64 bit (review comment by Chris) - Use of_match_ptr() (review comments by Chris) - Minor checkpatch cleanups Chris: To actually make use of this with 16 bit width, you'd need to add a new DT compatible, which could be done in a follow up patch. Is your SoC considered a armada-xp variant?
