Blackfin: unify u-boot linker scripts
All the Blackfin linker scripts were duplicated across the board dirs with no difference save from the semi-often used ENV_IS_EMBEDDED option. So unify all of them in the lib_blackfin/ dir and for the few boards that need to embedded the environment directly, add a LDS_BOARD_TEXT define for them to customize via their board config file. This is much simpler than forcing them to duplicate the rest of the linker script. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
