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 configs/*/include
directory; 'chip' will be a link to the SH chip sub-directory.
