 * The Toshiba configuration interface is composed of the HCI and the SCI,
 * which are defined as follows:
 *
 * HCI is Toshiba's "Hardware Control Interface" which is supposed to
 * be uniform across all their models.  Ideally we would just call
 * dedicated ACPI methods instead of using this primitive interface.
 * However the ACPI methods seem to be incomplete in some areas (for
 * example they allow setting, but not reading, the LCD brightness value),
 * so this is still useful.
 *
 * SCI stands for "System Configuration Interface" which aim is to
 * conceal differences in hardware between different models.
