firmware: scmi: correct a validity check against power domain id

2023-11-10T15:59:28Z

A power domain id on sandbox should be in the range from zero to ARRAY_SIZE(scmi_pwdom) - 1. Correct the validity check logic. Addresses-Coverity-ID: 467401 ("Out-of-bounds write") Addresses-Coverity-ID: 467405 ("Out-of-bounds read") Signed-off-by: AKASHI Takahiro

sandbox: add SCMI power domain protocol support for testing

2023-10-24T21:05:24Z

SCMI power domain management protocol is supported on sandbox for test purpose. Add fake agent interfaces and associated power domain devices. Signed-off-by: AKASHI Takahiro Reviewed-by: Simon Glass

power: domain: add SCMI driver

Add power domain driver based on SCMI power domain management protocol. Signed-off-by: AKASHI Takahiro

firmware: scmi: add power domain protocol support

2023-10-24T21:05:24Z

In this patch, added are helper functions to directly manipulate SCMI power domain management protocol. DM compliant power domain driver will be implemented on top of those interfaces in a succeeding patch. Signed-off-by: AKASHI Takahiro

firmware: scmi: Fix clearing variable

2023-10-14T01:21:07Z

The sess variable in open_channel was not entirely cleared to zero at the start of this function. This commit ensures that the entire struct is cleared. Signed-off-by: Francois Berder

firmware: scmi: add a check against availability of protocols

2023-10-13T20:59:24Z

Now that we have Base protocol support, we will be able to check if a given protocol is really supported by the SCMI server (firmware). Signed-off-by: AKASHI Takahiro Reviewed-by: Etienne Carriere Reviewed-by: Simon Glass

firmware: scmi: install base protocol to SCMI agent

2023-10-13T20:59:24Z

SCMI base protocol is mandatory, and once SCMI node is found in a device tree, the protocol handle (udevice) is unconditionally installed to the agent. Then basic information will be retrieved from SCMI server via the protocol and saved into the agent instance's local storage.

test: dm: simplify SCMI unit test on sandbox

2023-10-13T20:59:24Z

Adding SCMI base protocol makes it inconvenient to hold the agent instance (udevice) locally since the agent device will be re-created per each test. Just remove it and simplify the test flows. The test scenario is not changed at all. Signed-off-by: AKASHI Takahiro Reviewed-by: Simon Glass Reviewed-by: Etienne Carriere

firmware: scmi: fake base protocol commands on sandbox

2023-10-13T20:59:23Z

This is a simple implementation of SCMI base protocol for sandbox. The main use is in SCMI unit test. Signed-off-by: AKASHI Takahiro Reviewed-by: Simon Glass Reviewed-by: Etienne Carriere

firmware: scmi: add a version check against base protocol

2023-10-13T20:59:23Z

In SCMI base protocol version 2 (0x20000), new interfaces, BASE_SET_DEVICE_PERMISSIONS/BASE_SET_PROTOCOL_PERMISSIONS/ BASE_RESET_AGENT_CONFIGURATION, were added. Moreover, the api of BASE_DISCOVER_AGENT was changed to support self-agent discovery. So the driver expects SCMI firmware support version 2 of base protocol.
