* With the addition of serdbg, the standard polled I/O functions for gdbstub and/or printk are optionally routed to any termios-aware device driver, that supports polled mode. See libmisc/serdbg/README. * serdbg/Makefile.am, serdbg/README, serdbg/serdbg.c, serdbg/serdbg.h, serdbg/serdbgcnf.h, serdbg/serdbgio.c, serdbg/termios_printk.c, serdbg/termios_printk.h, serdbg/termios_printk_cnf.h, serdbg/.cvsignore: New files. * configure.ac, Makefile.am, wrapup/Makefile.am: Modified to reflect addition.
