+ * blockframe.c (inside_main_func): Cleanup slightly. Move
+ mainsym def into the block it's used in.
+ * configure.in configure: Allow NATDEPFILES to be recognized in
+ .mh files regardless of whitespace.
+
+ * cpu32bug-rom.c (cpu32bug_cmds): Change load_response string to
+ keep downloads from hanging.
+
+ * remote-wiggler.c: Add support for flash upgrades.
+ * (wiggler_error): Fix message format. Add new error code.
+ * (wiggler_write_byets): Error code is hex. Report errors with
+ proper routine name.
+ * (wiggler_read_byets): Report errors with proper routine name.
+ * (get_packet): Add support for new flash commands.
+ * (wiggler_load): Call clear_symtab_users() to reset things
+ properly after download.
+ * (flash_xfer_memory bdm_update_flash_command): New funxtions to
+ support flash upgrades for Wiggler.
+ * (_initialize_remote_wiggler): Add `bdm update-flash' command.
