i2c-vr: add support for MPS MP994X VR firmware update over I2C
This commit introduces support for programming MPS MP994X VR devices
over the I2C bus. It enables firmware updates for VR models such as
MP9945 and MP9946.
Support for the MP994XFirmware type in EM was added in [1].
[1] https://gerrit.openbmc.org/c/openbmc/entity-manager/+/84276
Tested on the Yosemite5 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/Yosemite5_MB_VR_18_S5_3671"
},
{...}
],
"Members@odata.count": 12,
"Name": "Software Inventory Collection"
}
```
2. Query version.
```
curl $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory/Yosemite5_MB_VR_18_S5_3671
```
```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Yosemite5_MB_VR_18_S5_3671",
"@odata.type": "#SoftwareInventory.v1_1_0.SoftwareInventory",
"Description": "Other image",
"Id": "Yosemite5_MB_VR_18_S5_3671",
"Name": "Software Inventory",
"Status": {
"Health": "OK",
"HealthRollup": "OK",
"State": "Enabled"
},
"Updateable": true,
"Version": "61A5F378"
}
```
3. Trigger the fw update via redfish.
```
curl -k ${creds} \
-H "Content-Type:multipart/form-data" \
-X POST \
-F UpdateParameters="{\"Targets\":[\"/redfish/v1/UpdateService/FirmwareInventory/Yosemite5_MB_VR_18_S5_3671\"],\"@Redfish.OperationApplyTime\":\"OnReset\"};type=application/json" \
-F "UpdateFile=@${fwpath};type=application/octet-stream" \
https://${bmc}/redfish/v1/UpdateService/update-multipart
```
4. Task is returned
```

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/Yosemite5_MB_VR_18_S5_2390"
},
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Yosemite5_MB_VR_18_S5_3671"
},
{...}
],
"Members@odata.count": 13,
"Name": "Software Inventory Collection"
}
```
7. Query the new fw version.
```
curl $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory/Yosemite5_MB_VR_18_S5_2390
```
```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Yosemite5_MB_VR_18_S5_2390",

```
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
```
```
kevin@meta-device:~$ curl --silent $creds https://$bmc/redfish/v1/UpdateService/FirmwareInventory
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory",
"@odata.type": "#SoftwareInventoryCollection.SoftwareInventoryCollection",
"Members": [
{...},

},
{...}
],
"Members@odata.count": 12,
"Name": "Software Inventory Collection"
}
```
10. Query the fw version after AC cycle.
```
