Subject: [PATCH] Blackfin arch: cplb and map header file cleanup
- remove duplicated defines for the BF561
- generalize L2 support (so that it works for BF54x) and mark it executable
- add support for reading/executing the Boot ROM sections
(since it has data/functions we may need at runtime)
- and fixup names for each map
