[1] https://gerrit.openbmc.org/c/openbmc/entity-manager/+/83114

Tested on the Santabarbara platform:

1. Display the fw inventory
```
curl --silent $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory
```

```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory",
"@odata.type": "#SoftwareInventoryCollection.SoftwareInventoryCollection",
"Members": [
{...},
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_8692"
},
{...}
],
"Members@odata.count": 13,
"Name": "Software Inventory Collection"
}
```

2. Query version.
```
curl $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_8692
```

```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_8692",
"@odata.type": "#SoftwareInventory.v1_1_0.SoftwareInventory",
"Description": "Unknown image",
"Id": "Santabarbara_PDB2_VR_MP5998_8692",
"Name": "Software Inventory",
"Status": {
"Health": "OK",
"HealthRollup": "OK",
"State": "Enabled"
},
"Updateable": true,
"Version": "508F"
}
```

3. Trigger the fw update via redfish.
```
curl -k ${creds} \
-H "Content-Type:multipart/form-data" \
-X POST \
-F UpdateParameters="{"Targets":["/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_8692"],"@Redfish.OperationApplyTime":"OnReset"};type=application/json" \
-F "UpdateFile=@${fwpath};type=application/octet-stream" \
https://${bmc}/redfish/v1/UpdateService/update-multipart
```

4. Task is returned
```
{
"@odata.id": "/redfish/v1/TaskService/Tasks/0",
"@odata.type": "#Task.v1_4_3.Task",
"HidePayload": false,
"Id": "0",
"Messages": [
{
"@odata.type": "#Message.v1_1_1.Message",
"Message": "The task with Id '0' has started.",

"TaskMonitor": "/redfish/v1/TaskService/TaskMonitors/0",
"TaskState": "Running",
"TaskStatus": "OK"
}
```

5. Query Task status
```
curl --silent $creds https://$bmc/redfish/v1/TaskService/Tasks/0
```

```
{
"@odata.id": "/redfish/v1/TaskService/Tasks/0",
"@odata.type": "#Task.v1_4_3.Task",
"EndTime": "2025-08-22T08:41:48+00:00",

6. Display the fw inventory with newly updated fw.
```
curl --silent $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory
```

```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory",
"@odata.type": "#SoftwareInventoryCollection.SoftwareInventoryCollection",
"Members": [
{...},
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_5612"
},
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_8692"
},
{...}
],
"Members@odata.count": 16,
"Name": "Software Inventory Collection"
}
```

7. Query the new fw version.
```
curl $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_5612
```

```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_5612",
"@odata.type": "#SoftwareInventory.v1_1_0.SoftwareInventory",
"Description": "Unknown image",
"Id": "Santabarbara_PDB2_VR_MP5998_5612",

"Status": {
"Health": "OK",
"HealthRollup": "OK",
"State": "Enabled"
},
"Updateable": false,
"Version": "FCFF"

```

8. Do AC cycle to make sure the new fw is applied.
```
busctl set-property xyz.openbmc_project.State.Chassis0 /xyz/openbmc_project/state/chassis0 \
xyz.openbmc_project.State.Chassis RequestedPowerTransition s xyz.openbmc_project.State.Chassis.Transition.PowerCycle
```

9. Display the fw inventory after AC cycle.
```
curl --silent $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory
```

```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory",
"@odata.type": "#SoftwareInventoryCollection.SoftwareInventoryCollection",
"Members": [
{...},
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_302"
},
{...}
],
"Members@odata.count": 12,
"Name": "Software Inventory Collection"
}
```

10. Query the fw version after AC cycle.
```
curl $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_302
```

```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Santabarbara_PDB2_VR_MP5998_302",
