Not in -ptx: 

#ifdef CONFIG_VFD
[...]
#else
        /* FIXME: shouldn't the board info structure be between malloc      */
        /* area and u-boot code?                                            */

        /* malloc area is below startaddress of u-boot in RAM */
        mem_malloc_init(_armboot_start - CFG_MALLOC_LEN);
#endif /* CONFIG_VFD */
