* Makefile.am, configure.ac, include/bsp.h, startup/hw_init.c, startup/linkcmds, startup/linkcmds-le, startup/linkcmds-le.coff: Use shared bsp_get_work_area() in its own file and rely on BSP Framework to perform more initialization. After factoring this out, it turned out that all SuperH BSPs has the same bsp_start() implementation so this was made shared. * startup/bspstart.c: Removed.
