  16           U-Boot expects to be linked to a specific hard-coded address, and to
  17           be loaded to and run from that address. This option lifts that
  18           restriction, thus allowing the code to be loaded to and executed
  19           from almost any address. This logic relies on the relocation
  20           information that is embedded into the binary to support U-Boot
  21           relocating itself to the top-of-RAM later during execution.

  25         help
  26           U-Boot typically uses a hard-coded value for the stack pointer
  27           before relocation. Define this option to instead calculate the
  28           initial SP at run-time. This is useful to avoid hard-coding addresses
  29           into U-Boot, so that can be loaded and executed at arbitrary
  30           addresses and thus avoid using arbitrary addresses at runtime. This
  31           option's value is the offset added to &_bss_start in order to
  32           calculate the stack pointer. This offset should be large enough so
  33           that the early malloc region, global data (gd), and early stack usage
  34           do not overlap any appended DTB.

  40           The format of the header is described in the Linux kernel source at
  41           Documentation/arm64/booting.txt. This feature is useful since the
  42           image header reports the amount of memory (BSS and similar) that
  43           U-Boot needs to use, but which isn't part of the binary.
