+         Interface) is used mostly on x86 for providing information to the
+         Operating System about devices in the system. The tables are set up
+         by the firmware, typically U-Boot but possibly an earlier firmware
+         module, if U-Boot is chain-loaded from something else. ACPI tables
+         can also include code, to perform hardware-specific tasks required
+         by the Operating Systems. This allows some amount of separation
+         between the firmware and OS, and is particularly useful when you
+         want to make hardware changes without the OS needing to be adjusted.
