 * below this.
 *
 * This function requires a stack[1] Normally this is at @top. The function
 * starts allocating space from 64 bytes below @top. First it creates space
 * for global_data. Then it calls arch_setup_gd() which sets gd to point to
 * the global_data space and can reserve additional bytes of space if
 * required). Finally it allocates early malloc() memory
 * (CONFIG_SYS_MALLOC_F_LEN). The new top of the stack is just below this,
 * and it returned by this function.
 *
 * [1] Strictly speaking it would be possible to implement this function
 * in C on many archs such that it does not require a stack. However this
 * does not seem hugely important as only 64 byte are wasted. The 64 bytes
 * are used to handle the calling standard which generally requires pushing
 * addresses or registers onto the stack. We should be able to get away with
 * less if this becomes important.
