Just a remark: There is a tool called shgen inside the source-tree
(c/src/exec/score/tools/sh/shgen.c in RTEMS-4.0.0) which generates some tables
and functions for the sh7032's on-chip serial devices. These tables and functions
are designed to serve a internal subroutines to compute some internal settings
for serial drivers and should be useful to support termios.
