+               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.
+
+               This feature allocates regions with increasing addresses
+               within the region. calloc() is supported, but realloc()
+               is not available. free() is supported but does nothing.
+               The memory will be freed (or in fact just forgotten) when
+               U-Boot relocates itself.
