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?
Chris Packham (2):
ARM: l2x0: support parity-enable/disable on aurora
ARM: l2x0: add arm,ecc-enable property for aurora
Jan Luebbe (6):
ARM: l2c: move cache-aurora-l2.h to asm/hardware
ARM: aurora-l2: add prefix to MAX_RANGE_SIZE
EDAC: Add missing debugfs_create_x32 wrapper
EDAC: Add devres helpers for
edac_mc_alloc/edac_mc_add_mc(_with_groups)
EDAC: Add devres helpers for
edac_device_alloc_ctl_info/edac_device_add_device
EDAC: Add driver for the Marvell Armada XP SDRAM and L2 cache ECC
