Add support for ARM System Control and Management Interface (SCMI) v3.1. 2022-12-19T22:28:21+00:00 Ruslan Bukin br@FreeBSD.org 2022-12-19T20:16:18+00:00 54b96380f5774c1754a0fcf25212fa8e01db74f6 The SCMI specification describes a set of standard interfaces for power, performance and system management. SCMI is extensible and provides interfaces to access functions which are often implemented in firmwares in the System Control Processor (SCP). This implements Shared Memory-based transfer, which is one of the ways on how messages are exchanged between agents and the platform. This includes a driver for ARM Message Handling Unit (MHU) Doorbell, which is a mechanism that the caller can use to alert the callee of the presence of a message. The support implements clock management interface. For instance this allows us to control HDMI pixel clock on ARM Morello Board. Tested on ARM Morello Board.
