| help |
| Say Y here to only use the *_simple malloc functions from |
| malloc_simple.c, rather then using the versions from dlmalloc.c; |
| this will make the SPL binary smaller at the cost of more heap |
| usage as the *_simple malloc functions do not re-use free-ed mem. |

| 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. |

| help |
| Specify the amount of the stack to use as memory pool for |
| malloc_simple after switching the stack to DRAM. This may be set |
| to give board_init_r() a larger heap then the initial heap in |
| SRAM which is limited to SYS_MALLOC_F_LEN bytes. |

| config SPL_SEPARATE_BSS |

| bool "BSS section is in a different memory region from text" |
| help |
| 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 |
| location is used. Normally we put the device tree at the end of BSS |
| but with this option enabled, it goes at _image_binary_end. |
