+ * 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.
