config SPL
bool
depends on SUPPORT_SPL
prompt "Enable SPL"
help
If you want to build SPL as well as the normal image, say Y.
config SPL_SYS_MALLOC_SIMPLE
bool
depends on SPL
prompt "Only use malloc_simple functions in the SPL"
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
depends on SPL
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.
config SPL_STACK_R_ADDR
depends on SPL_STACK_R
hex "SDRAM location for SPL stack"
help
Specify the address in SDRAM for the SPL stack. This will be set up
before board_init_r() is called.
config SPL_STACK_R_MALLOC_SIMPLE_LEN
depends on SPL_STACK_R && SPL_SYS_MALLOC_SIMPLE
hex "Size of malloc_simple heap after switching to DRAM SPL stack"
default 0x100000
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
depends on SPL
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.
config TPL
