lib: utils: Add cache flush library

2025-10-28T05:09:59Z

The current RISC-V CMO only defines how to flush a cache block. However, certain use cases, such as power management, may require flushing the entire cache. Therefore, a framework is being introduced to allow vendors to flush the entire cache using their own methods.

lib: utils/mailbox: Add generic mailbox library

2024-12-06T03:56:13Z

Add generic mailbox library which is independent of hardware description format. The OpenSBI platform support or mailbox drivers can register mailbox controller instances which can be discovered and used by different mailbox client drivers. Each mailbox controller instance has a unique ID which can be used by mailbox client drivers for find the mailbox controller instance. The mailbox client drivers will typically request a mailbox channel from the mailbox controller and use it to do data transfer with the remote end of mailbox channel. Signed-off-by: Anup Patel
