Many aspects of the Blackfin memory map is exactly the same across all variants. Rather than copy and paste all of these duplicated values in each header, unify all of these into the common Blackfin memory map header file. In the process, push down BF561 SMP specific stuff to the BF561 specific header to keep the noise down. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
