Function Documentation

EFI_STATUS EFIAPI BuildSsdtSerialPortTable	(	IN CONST CM_STD_OBJ_ACPI_TABLE_INFO *	AcpiTableInfo,
		IN CONST CM_ARM_SERIAL_PORT_INFO *	SerialPortInfo,
		IN CONST CHAR8 *	Name,
		IN CONST UINT64	Uid,
		OUT EFI_ACPI_DESCRIPTION_HEADER **	Table
	)

Build a SSDT table describing the input serial port.

The table created by this function must be freed by FreeSsdtSerialTable.

Parameters

[in]	AcpiTableInfo	Pointer to the ACPI table information.
[in]	SerialPortInfo	Serial port to describe in the SSDT table.
[in]	Name	The Name to give to the Device. Must be a NULL-terminated ASL NameString e.g.: "DEV0", "DV15.DEV0", etc.
[in]	Uid	UID for the Serial Port.
[out]	Table	If success, pointer to the created SSDT table.

Return values

EFI_SUCCESS	Table generated successfully.
EFI_INVALID_PARAMETER	A parameter is invalid.
EFI_NOT_FOUND	Could not find information.
EFI_OUT_OF_RESOURCES	Could not allocate memory.

EFI_STATUS EFIAPI FreeSsdtSerialPortTable ( IN EFI_ACPI_DESCRIPTION_HEADER * Table )

Free an SSDT table previously created by the BuildSsdtSerialTable function.

Parameters

[in] Table Pointer to a SSDT table allocated by the BuildSsdtSerialTable function.

Return values

EFI_SUCCESS Success.

EFI_STATUS EFIAPI ValidateSerialPortInfo	(	IN CONST CM_ARM_SERIAL_PORT_INFO *	SerialPortInfoTable,
		IN UINT32	SerialPortCount
	)

Validate the Serial Port Information.

Parameters

[in]	SerialPortInfoTable	Table of CM_ARM_SERIAL_PORT_INFO.
[in]	SerialPortCount	Count of SerialPort in the table.

Return values

EFI_SUCCESS	Success.
EFI_INVALID_PARAMETER	Invalid parameter.
