U-Boot typically uses a hard-coded value for the stack pointer

+ before relocation. Enable this option to instead calculate the
initial SP at run-time. This is useful to avoid hard-coding addresses
into U-Boot, so that can be loaded and executed at arbitrary
- addresses and thus avoid using arbitrary addresses at runtime. This
- option's value is the offset added to &_bss_start in order to
+ addresses and thus avoid using arbitrary addresses at runtime.

+ If this option is enabled, the early stack pointer is set to
+ &_bss_start with a offset value added. The offset is specified by
