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. |

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. |
