The ARM bsp families are a little bit different from the others (has
newer features / software architecture) so be aware that there may be
some issues that have not been well documented in the BSP how-to. If
you run into something that is unfamiliar just ask here or on the
rtems-devel list. When you get around to having code to submit please
post patches to rtems-devel, or through rtems bugzilla.
