+ * care about what is in the stack. If we are smart we set
+ * the CAR stack to the same location as the rest of
+ * coreboot. If that is the case we can just do a wbinvd.
+ * The stack will be written into real RAM that is now setup
+ * and we continue like nothing happened. If the stack is
+ * located somewhere other than where LB would like it, you
+ * need to write some code to do a copy from cache to RAM
