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.

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.

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.
