13 config POSITION_INDEPENDENT
14 bool "Generate position-independent pre-relocation code"
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.
23 config INIT_SP_RELATIVE
24 bool "Specify the early stack pointer relative to the .bss section"
26 U-Boot typically uses a hard-coded value for the stack pointer
27 before relocation. Enable 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.
32 If this option is enabled, the early stack pointer is set to
33 &_bss_start with a offset value added. The offset is specified by
34 SYS_INIT_SP_BSS_OFFSET.
36 config SYS_INIT_SP_BSS_OFFSET
37 int "Early stack offset from the .bss base address"
38 depends on INIT_SP_RELATIVE
41 This option's value is the offset added to &_bss_start in order to
42 calculate the stack pointer. This offset should be large enough so
43 that the early malloc region, global data (gd), and early stack usage
44 do not overlap any appended DTB.
46 config LINUX_KERNEL_IMAGE_HEADER
49 Place a Linux kernel image header at the start of the U-Boot binary.
50 The format of the header is described in the Linux kernel source at
51 Documentation/arm64/booting.txt. This feature is useful since the
52 image header reports the amount of memory (BSS and similar) that
53 U-Boot needs to use, but which isn't part of the binary.
