14	bool "Generate position-independent pre-relocation code"
15	help
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.
22
23config SYS_INIT_SP_BSS_OFFSET
24	int
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.
35
36config LINUX_KERNEL_IMAGE_HEADER
37	bool
38	help
39	  Place a Linux kernel image header at the start of the U-Boot binary.
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.
