This board is based on Intel Tangier SoC (Intel Merrifield platform) and may utilize ACPI powerfulness.
Bring minimum support by appending initial DSDT table for it.
Note, the addresses for generated tables are carefully chosen to avoid any conflicts with existing shadowed BIOS data. The user have somewhat like ~31 kB available for compiled ACPI tables that ought to be enough.
