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

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

51# @data: colon (:) separated list of pathnames to load and
52#        concatenate as table data. The resultant binary blob must not have an
