+#
+# Specify an ACPI table on the command line to load.
+#
+# At most one of @file and @data can be specified. The list of files specified
+# by any one of them is loaded and concatenated in order. If both are omitted,
+# @data is implied.
+#
+# Other fields / optargs can be used to override fields of the generic ACPI
+# table header; refer to the ACPI specification 5.0, section 5.2.6 System
+# Description Table Header. If a header field is not overridden, then the
+# corresponding value from the concatenated blob is used (in case of @file), or
+# it is filled in with a hard-coded value (in case of @data).
+#
+# String fields are copied into the matching ACPI member from lowest address
+# upwards, and silently truncated / NUL-padded to length.
+#
+# @sig: table signature / identifier (4 bytes)
+#
+# @rev: table revision number (dependent on signature, 1 byte)
