[patch v3 0/4] Add edac driver for i.MX8MP based on synopsys edac driver

From: Sherry Sun
Date: Wed Apr 01 2020 - 21:28:28 EST


This patchset add edac driver support for i.MX8MP, since i.MX8MP use the same
synopsys memory controller with ZynqMP, so the driver is based on synopsys_edac
driver.

Considering that i.MX8MP dts file is still in kernel/git/shawnguo/linux.git and
isn't in mainline now, I will add EDAC node in i.MX8MP dts after this file is
pushed to mainline.

And the edac driver for i.MX8MP has been tested in kernel/git/shawnguo/linux.git
where i.MX8MP is supported, it turns out that this driver works well to detect
corrected and uncorrected errors for LPDDR4 in i.MX8MP.

Changes since v2:
=================
- Use u64 data instead u32 data_low and u32 data_high as robert suggested in
patch 4/4.
- Add edac_dbg() for the != DEV_X8 cases in zynqmp_get_error_info() in patch
4/4.
- Change the format of the output data to avoid build warnings in patch 4/4.

Changes since v1:
=================
- Reorganized the patchset, no content changes.
