+ SPL starts off execution in SRAM and thus typically has only a small

+ function, it is possible for the stack to move there before
+ board_init_r() is reached. This option enables a special SDRAM
+ location for the SPL stack. U-Boot SPL switches to this after
+ board_init_f() completes, and before board_init_r() starts.
