/**
Executes an SMBus operation to an SMBus controller. Returns when either the command has been
executed or an error is encountered in doing the operation.
The SmbusExecute() function provides a standard way to execute an operation as defined in the System
Management Bus (SMBus) Specification. The resulting transaction will be either that the SMBus
slave devices accept this transaction or that this function returns with error.
@param SmbusAddress Address that encodes the SMBUS Slave Address, SMBUS Command, SMBUS Data Length,
and PEC.
@param Operation Signifies which particular SMBus hardware protocol instance that
it will use to execute the SMBus transactions. This SMBus
hardware protocol is defined by the SMBus Specification and is
not related to EFI.
@param Length Signifies the number of bytes that this operation will do. The
maximum number of bytes can be revision specific and operation
specific. This field will contain the actual number of bytes that
are executed for this operation. Not all operations require this
argument.
@param Buffer Contains the value of data to execute to the SMBus slave device.
Not all operations require this argument. The length of this
buffer is identified by Length.
@retval EFI_SUCCESS The last data that was returned from the access matched the poll
exit criteria.
@retval EFI_CRC_ERROR Checksum is not correct (PEC is incorrect).
@retval EFI_TIMEOUT Timeout expired before the operation was completed. Timeout is
determined by the SMBus host controller device.
@retval EFI_OUT_OF_RESOURCES The request could not be completed due to a lack of resources.
@retval EFI_DEVICE_ERROR The request was not completed because a failure that was
reflected in the Host Status Register bit. Device errors are a
result of a transaction collision, illegal command field,
unclaimed cycle (host initiated), or bus errors (collisions).
@retval EFI_INVALID_PARAMETER Operation is not defined in EFI_SMBUS_OPERATION.
@retval EFI_INVALID_PARAMETER Length/Buffer is NULL for operations except for EfiSmbusQuickRead
and EfiSmbusQuickWrite. Length is outside the range of valid
values.
@retval EFI_UNSUPPORTED The SMBus operation or PEC is not supported.
@retval EFI_BUFFER_TOO_SMALL Buffer is not sufficient for this operation.
