lib: utils: Mark RPMI drivers as experimental

2024-12-21T12:52:47Z

These drivers were merged on an experimental basis without the RPMI specification being frozen. As a result, they may not be compatible with the frozen version of the RPMI protocol. Additionally, their devicetree bindings have not been reviewed and are subject to change. Warn the user that these drivers make no compatibility guarantees, and that their behavior and devicetree bindings may change incompatibly in future versions of OpenSBI.

lib/utils: reset: Add RPMI System Reset driver

lib: utils/reset: Use fdt_driver for initialization

2024-11-28T12:18:17Z

The reset driver subsystem does not need any extra data, so it can use `struct fdt_driver` directly. The generic fdt_reset_init() performs a best-effort initialization of all matching DT nodes. Platform-specific logic expects exactly one DT node to match a single driver. This is accomplished by using fdt_driver_init_one() with a local list containing that one driver.

treewide: Make carray arrays const and NULL-terminated

2024-11-28T11:39:17Z

This allows the compiler to generate significantly better code, because it does not have to maintain either the loop counter or loop limit. Plus there are half as many symbols to relocate. This also simplifies passing carray arrays to helper functions. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: utils/reset: Pass the FDT to fdt_reset_init()

2024-08-24T07:32:58Z

Indicate that this function does not modify the FDT blob, and deduplicate the call to fdt_get_address(). Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: utils/reset: Constify FDT pointers in parsing functions

2024-08-24T07:32:42Z

Indicate that none of these functions modify the devicetree by constifying the parameter type. Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

Makefile: change to using .carray.c for carray files

2024-07-04T06:41:45Z

We would like to clean any files generated by the carray scripts by just searching for the filename as the current make system turns f.carray into f.o. Change to make the make system turn f.carray into f.carray.o note, command to go through .mk files changing the .o in the .mk files is: find . -type f -name "*.carray" | xargs -t -I fname /bin/bash -x -c ' fn=`basename -s .carray fname`; echo "$fn"; sed -i `dirname fname `/objects.mk -e s/"$fn".o/"$fn".carray.o/g' Link: https://patchwork.ozlabs.org/project/opensbi/patch/20240401213438.590209-2-ivan.orlov0322@gmail.com/ Reported-by: Ivan Orlov Suggested-by: Andrew Jones Signed-off-by: Ben Dooks Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: utils/reset: Try initializing all reset devices in dt

2024-06-13T16:18:03Z

In DT, multiple reset devices may use the same driver, and they may have different priorities. If rc is returned after the first initialization, the highest priority device may be lost.
