# @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
