Subject: Switch to using a shared main() for all of the embedded BSPs based on
 the GNU tools.  This usually involved correcting the type of bsp_start(),
 bsp_cleanup(), adjusting the start code to call the right start routine (the
 shared boot_card()), and then removing code from bsp_start() which was
 performed in the new boot_card()/main() path.
