-/**
- 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.

- This is an function to close the S3 boot script table. The function could only be called in
- BOOT time phase. To comply with the Framework spec definition on
- EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable(), this function will fulfill following things:
- 1. Closes the specified boot script table
- 2. It allocates a new memory pool to duplicate all the boot scripts in the specified table.
- Once this function is called, the table maintained by the library will be destroyed
- after it is copied into the allocated pool.
- 3. Any attempts to add a script record after calling this function will cause a new table
- to be created by the library.
- 4. The base address of the allocated pool will be returned in Address. Note that after
- using the boot script table, the CALLER is responsible for freeing the pool that is allocated
- by this function.
-
- In Spec PI1.1, this EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is retired. To provides this API for now is
- for Framework Spec compatibility.
-
- If anyone does call CloseTable() on a real platform, then the caller is responsible for figuring out
- how to get the script to run at S3 resume because the boot script maintained by the lib will be
- destroyed.
-
- @return the base address of the new copy of the boot script table.
- @note this function could only called in boot time phase
