How to set I2C host controller address/input clock frequency for MinnowBoard?

[gordontcp]

In 'MdeModulePkg\Bus\I2c\I2cDxe', since the following protocol is not installed:

gEfiI2cMasterProtocolGuid
gEfiI2cEnumerateProtocolGuid
gEfiI2cBusConfigurationManagementProtocolGuid

So I refer to the example of \edk2-platforms\Silicon\Marvell\Drivers\I2c\MvI2cDxe and add the following related items

Status = gBS->InstallMultipleProtocolInterfaces(
&I2cMasterContext->Controller,
&gEfiI2cMasterProtocolGuid,
&I2cMasterContext->I2cMaster,
&gEfiI2cEnumerateProtocolGuid,
&I2cMasterContext->I2cEnumerate,
&gEfiI2cBusConfigurationManagementProtocolGuid,
&I2cMasterContext->I2cBusConf,
&gEfiDevicePathProtocolGuid,
(EFI_DEVICE_PATH_PROTOCOL *) DevicePath,
NULL);

In addition, use the following methods to obtain gI2CIO in the app,

Status = gBS->LocateHandleBuffer(
ByProtocol,
&gEfiI2cIoProtocolGuid,
NULL,
&HandleCount,
&I2CIOHandleBuffer
);
for (HandleIndex = 0; HandleIndex < HandleCount; HandleIndex++)
{
Status = gBS->HandleProtocol(
I2CIOHandleBuffer[HandleIndex],
&gEfiI2cIoProtocolGuid,
(VOID**)&gI2CIO);
}

Then use the following methods to perform I2C IO operations.
I2cIo->QueueRequest(I2cIo, 0, NULL, RequestPacket, NULL);
But finally I saw the following message, and measured by LA, I2C IO did not send data:
MvI2cDxe: wrong I2cStatus (00) after sending START condition
message from

MvI2cLockedStart (
IN I2C_MASTER_CONTEXT *I2cMasterContext,
IN INT32 Mask,
IN UINT8 Slave,
IN UINTN Timeout
)
{
 …
I2cStatus = I2C_READ(I2cMasterContext, I2C_STATUS);
if ((INT32)I2cStatus != Mask) {
DEBUG((DEBUG_ERROR, "MvI2cDxe: wrong I2cStatus (%02x) after sending %sSTART condition\n", I2cStatus, Mask == I2C_STATUS_START ? "" : "repeated "));
return EFI_DEVICE_ERROR;
}

Where I2C_READ is defined as follows:

STATIC
UINT32
I2C_READ(
IN I2C_MASTER_CONTEXT *I2cMasterContext,
IN UINTN off)
{
return MmioRead32 (I2cMasterContext->BaseAddress + off);
}

My environment is as follows

Platform: MinnowBoard max
Code: edk2-platforms\Platform\Intel\Vlv2TbltDevicePkg

My questions are as follows:

1. In MinnowBoard, can MmioRead32 (I2cMasterContext->BaseAddress + off) IO operations be performed directly like MvI2cDxe?
2. How to set BaseAddress(host controller address) in MinnowBoard?
3. How to set Controller’s input clock frequency?
4. Are there other examples of the I2C master protocol for reference?
   Any advice is greatly appreciated!
   Thanks!
