13# @AcpiTableOptions:
14#
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.

47# @file: colon (:) separated list of pathnames to load and concatenate
48#     as table data.  The resultant binary blob is expected to have an
49#     ACPI table header.  At least one file is required.  This field
50#     excludes @data.
