  *
  * OUTPUT_FORMAT(...)
  * OUTPUT_ARCH(...)
  * ENTRY(...)
  * SECTIONS
  * {

  * }
  *
  * [__init_begin, __init_end] is the init section that may be freed after init
  * [_stext, _etext] is the text section
  * [_sdata, _edata] is the data section
  *
  * Some of the included output section have their own set of constants.
  * Examples are: [__initramfs_start, __initramfs_end] for initramfs and
  *               [__nosave_begin, __nosave_end] for the nosave data
