  15 # Specify an ACPI table on the command line to load.
  16 #
  17 # At most one of @file and @data can be specified.  The list of files
  18 # specified by any one of them is loaded and concatenated in order.
  19 # If both are omitted, @data is implied.
  20 #
  21 # Other fields / optargs can be used to override fields of the generic
  22 # ACPI table header; refer to the ACPI specification 5.0, section
  23 # 5.2.6 System Description Table Header.  If a header field is not
  24 # overridden, then the corresponding value from the concatenated blob
  25 # is used (in case of @file), or it is filled in with a hard-coded
  26 # value (in case of @data).
  27 #
  28 # String fields are copied into the matching ACPI member from lowest
  29 # address upwards, and silently truncated / NUL-padded to length.
