2 * Helper macros to support writing architecture specific
3 * linker scripts.
4 *
5 * A minimal linker scripts has following content:
6 * [This is a sample, architectures may have special requiriements]
7 *
8 * OUTPUT_FORMAT(...)
9 * OUTPUT_ARCH(...)
10 * ENTRY(...)
11 * SECTIONS
12 * {
13 * . = START;
14 * __init_begin = .;
15 * HEAD_TEXT_SECTION
16 * INIT_TEXT_SECTION(PAGE_SIZE)
17 * INIT_DATA_SECTION(...)
18 * PERCPU(PAGE_SIZE)
19 * __init_end = .;

33 * BSS_SECTION(0, 0, 0)
34 * _end = .;
35 *
36 * STABS_DEBUG
37 * DWARF_DEBUG
38 *
39 * DISCARDS // must be the last
40 * }
41 *
42 * [__init_begin, __init_end] is the init section that may be freed after init
43 * [_stext, _etext] is the text section
44 * [_sdata, _edata] is the data section
45 *
46 * Some of the included output section have their own set of constants.
47 * Examples are: [__initramfs_start, __initramfs_end] for initramfs and
48 * [__nosave_begin, __nosave_end] for the nosave data
