/// ## Secondary System Description Table
///
/// Secondary System Description Tables (SSDT) are a continuation of the DSDT.
/// The SSDT is comprised of a system description table header followed by data in Definition Block format. There can be multiple SSDTs present.
/// After OSPM loads the DSDT to create the ACPI Namespace, each secondary system description table listed in the RSDT/XSDT with a unique OEM Table ID is loaded in the order presented in the RSDT/XSDT.
///
/// Additional tables can only add data; they cannot overwrite data from previous tables.
///
/// This allows the OEM to provide the base support in one table and add smaller system options in other tables.
/// For example, the OEM might put dynamic object definitions into a secondary table such that the firmware can construct the dynamic information at boot without needing to edit the static DSDT.
/// A SSDT can only rely on the DSDT being loaded prior to it.
pub struct SecondarySystemDescriptionTable {
    /// - **Signature** - "SSDT"
    pub header: SDTHeader,
    /// The bytes of AML code.
    pub def_block: [u8; 0],
}
