EDAC/versal: Read num_csrows and num_chans using the correct bitfield macro

2023-12-15T12:01:27Z

Fix the extraction of num_csrows and num_chans. The extraction of the num_rows is wrong. Instead of extracting using the FIELD_GET it is calling FIELD_PREP. The issue was masked as the default design has the rows as 0.

EDAC/versal: Add a Xilinx Versal memory controller driver

2023-10-23T17:41:27Z

Add a EDAC driver for the RAS capabilities on the Xilinx integrated DDR Memory Controllers (DDRMCs) which support both DDR4 and LPDDR4/4X memory interfaces. It has four programmable Network-on-Chip (NoC) interface ports and is designed to handle multiple streams of traffic. The driver reports correctable and uncorrectable errors, and also creates debugfs entries for testing through error injection. [ bp: - Add a pointer to the documentation about the register unlock code. - Squash in a fix for a Smatch static checker issue as reported by Dan Carpenter: https://lore.kernel.org/r/a4db6f93-8e5f-4d55-a7b8-b5a987d48a58@moroto.mountain ] Co-developed-by: Sai Krishna Potthuri Signed-off-by: Sai Krishna Potthuri Signed-off-by: Shubhrajyoti Datta Signed-off-by: Borislav Petkov (AMD) Link: https://lore.kernel.org/r/20231005101242.14621-3-shubhrajyoti.datta@amd.com

EDAC/mc_sysfs: Replace deprecated strncpy() with memcpy()

2023-09-29T21:48:32Z

`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We've already calculated bounds, possible truncation with '\0' or '\n' and manually NUL-terminated. The situation is now just a literal byte copy from one buffer to another, let's treat it as such and use a less ambiguous interface in memcpy.

EDAC: Explicitly include correct DT includes

2023-08-28T18:31:01Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
