# @AcpiTableOptions:
#
# 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)
#
# @oem_id: OEM identifier (6 bytes)
#
# @oem_table_id: OEM table identifier (8 bytes)
#
# @oem_rev: OEM-supplied revision number (4 bytes)
#
# @asl_compiler_id: identifier of the utility that created the table
#                   (4 bytes)
#
# @asl_compiler_rev: revision number of the utility that created the
#                    table (4 bytes)
#
# @file: colon (:) separated list of pathnames to load and
#        concatenate as table data. The resultant binary blob is expected to
#        have an ACPI table header. At least one file is required. This field
#        excludes @data.
#
# @data: colon (:) separated list of pathnames to load and
#        concatenate as table data. The resultant binary blob must not have an
#        ACPI table header. At least one file is required. This field excludes
#        @file.
