+ 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.

+ 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.

+ 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.
