ram_addr_t must be large enough to address any address of the host. For hosts with sizeof(unsigned long) == sizeof(void *), this patch changes nothing. All currently supported hosts fall into this category. For w64 hosts, sizeof(unsigned long) is 4 while sizeof(void *) is 8, so the use of uintptr_t is needed.
