+config SPL_STACK_R
+ depends on SPL
+ bool "Enable SDRAM location for SPL stack"
+ help
+ SPL starts off execution in SRAM and thus typically has only a small
+ stack available. Since SPL sets up DRAM while in its board_init_f()
+ 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.

+config SPL_STACK_R_ADDR

+ hex "SDRAM location for SPL stack"
+ help
+ Specify the address in SDRAM for the SPL stack. This will be set up
+ before board_init_r() is called.
