| 18 | help |
| 19 | Say Y here to only use the *_simple malloc functions from |
| 20 | malloc_simple.c, rather then using the versions from dlmalloc.c; |
| 21 | this will make the SPL binary smaller at the cost of more heap |
| 22 | usage as the *_simple malloc functions do not re-use free-ed mem. |

| 24 | config SPL_STACK_R |

| 26 | bool "Enable SDRAM location for SPL stack" |
| 27 | help |
| 28 | SPL starts off execution in SRAM and thus typically has only a small |
| 29 | stack available. Since SPL sets up DRAM while in its board_init_f() |
| 30 | function, it is possible for the stack to move there before |
| 31 | board_init_r() is reached. This option enables a special SDRAM |
| 32 | location for the SPL stack. U-Boot SPL switches to this after |
| 33 | board_init_f() completes, and before board_init_r() starts. |

| 46 | help |
| 47 | Specify the amount of the stack to use as memory pool for |
| 48 | malloc_simple after switching the stack to DRAM. This may be set |
| 49 | to give board_init_r() a larger heap then the initial heap in |
| 50 | SRAM which is limited to SYS_MALLOC_F_LEN bytes. |

| 52 | config SPL_SEPARATE_BSS |
| 53 | depends on SPL |
| 54 | bool "BSS section is in a different memory region from text" |
| 55 | help |
| 56 | Some platforms need a large BSS region in SPL and can provide this |
| 57 | because RAM is already set up. In this case BSS can be moved to RAM. |
| 58 | This option should then be enabled so that the correct device tree |
| 59 | location is used. Normally we put the device tree at the end of BSS |
| 60 | but with this option enabled, it goes at _image_binary_end. |
