-config SPL_STACK_R

-	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.

-	  Some platforms need a large BSS region in SPL and can provide this

-	  This option should then be enabled so that the correct device tree
-	  location is used. Normally we put the device tree at the end of BSS
