                struct ACPI::RSDP

                Root System Description Pointer (RSDP)

                The first step to using ACPI is finding the RSDP that is used to find the RSDT / XSDT, which themselves contain pointers to even more tables.

                On UEFI systems, the RSDP can be found in the EFI_SYSTEM_TABLE; for non-UEFI systems we have to search for the signature 'RSD PTR ' in the EBDA (Extended Bios Data Area) or in the memory area up to FFFFFh.

                ACPI address format.

                The ACPI standard defines its own address format that is able to handle addresses both in memory address space, as well as IO-port address space.
