nuttx/arch/renesas/include

This directory contains header files common to all SH architectures.
Sub-directories within this directory contain header files unique to
specific SH chip architectures.  At configuration time, additional
directories will be linked here: 'build' will be a link to the
boards/renesas/<chip>/<board>/include directory; 'chip' will be a link to
the SH chip sub-directory.
