2025-09-16lib: utils/reset: Hang the hart after RPMI system reset messageRahul Pathak
RPMI system reset is a posted message which does not wait for acknowledgement after sending the RPMI message to PuC. Call the sbi_hart_hang() to hang the hart after performing the system reset via RPMI message.

2025-02-12lib: utils: Initialize miscellaneous drivers in one passSamuel Holland
For driver subsystems that are not tightly integrated into the OpenSBI init sequence, it is not important that the drivers are initialized in any particular order. By putting all of these drivers in one array, they can all be initialized with a single pass through the devicetree. This saves about 10 ms of boot time on HiFive Unmatched.

2024-12-21lib: utils: Mark RPMI drivers as experimentalSamuel Holland
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.
