- 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

- Some platforms need a large BSS region in SPL and can provide this
- because RAM is already set up. In this case BSS can be moved to RAM.
- This option should then be enabled so that the correct device tree
