This directory provides a build area for all SH architectures. The 'common' subdirectory contains source files shared by all SH architectures; Source files unique to a specific SH chip architecture are contained in a subdirectory named after the chip. At configuration time, additional directories will be linked here: 'build' will be a link to the configs/*/src directory; 'chip' will be a link to the SH chip sub-directory.
