Overview of the syntax of scatter-loading description files

A scatter_description is defined as one or more load_region_description patterns:

Scatter_description ::=

  load_region_description+

A load_region_description is defined as a load region name, optionally followed by attributes or size specifiers, and one or more execution region descriptions:

load_region_description ::=
    load_region_name (base_address | ("+" offset)) [attributes] [max_size]
    "{"
        execution_region_description+
    "}"

An execution_region_description is defined as an execution region name, a base address specification, optionally followed by attributes or size specifiers, and one or more input section descriptions:

execution_region_description ::=
    exec_region_name (base_address | "+" offset) [attribute_list][max_size | "–" length]
    "{"
        input_section_description*
    "}"

An input_section_description is defined as a source module selector pattern optionally followed by input section selectors:

input_section_description ::=
    module_select_pattern
        [ "(" input_section_selector ( "," input_section_selector )* ")" ]

input_section_selector ::=
    ("+" input_section_attr | input_section_pattern | input_symbol_pattern)
