13 config POSITION_INDEPENDENT
14 bool "Generate position-independent pre-relocation code"
15 select INIT_SP_RELATIVE
17 U-Boot expects to be linked to a specific hard-coded address, and to
18 be loaded to and run from that address. This option lifts that
19 restriction, thus allowing the code to be loaded to and executed
20 from almost any address. This logic relies on the relocation
21 information that is embedded in the binary to support U-Boot
22 relocating itself to the top-of-RAM later during execution.
24 config INIT_SP_RELATIVE
25 bool "Specify the early stack pointer relative to the .bss section"
27 U-Boot typically uses a hard-coded value for the stack pointer
28 before relocation. Enable this option to instead calculate the
29 initial SP at run-time. This is useful to avoid hard-coding addresses
30 into U-Boot, so that it can be loaded and executed at arbitrary
31 addresses and thus avoid using arbitrary addresses at runtime.
33 If this option is enabled, the early stack pointer is set to
34 &_bss_start with a offset value added. The offset is specified by
35 SYS_INIT_SP_BSS_OFFSET.
37 config SYS_INIT_SP_BSS_OFFSET
38 int "Early stack offset from the .bss base address"
39 depends on INIT_SP_RELATIVE
42 This option's value is the offset added to &_bss_start in order to
43 calculate the stack pointer. This offset should be large enough so
44 that the early malloc region, global data (gd), and early stack usage
45 do not overlap any appended DTB.
47 config LINUX_KERNEL_IMAGE_HEADER
50 Place a Linux kernel image header at the start of the U-Boot binary.
51 The format of the header is described in the Linux kernel source at
52 Documentation/arm64/booting.txt. This feature is useful since the
53 image header reports the amount of memory (BSS and similar) that
54 U-Boot needs to use, but which isn't part of the binary.
