Size of DRAM reserved for malloc() use.
+- CONFIG_SYS_MALLOC_F_LEN
+ Size of the malloc() pool for use before relocation. If
+ this is defined, then a very simple malloc() implementation
+ will become available before relocation. The address is just
+ below the global data, and the stack is moved down to make
+ space.
