c3a9f435ae 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

81a487a59f Blackfin arch: cleanup the cplb declares
- no need to declare their sizes in the common header
 - no need to tack on the section attribute as only the definition matters, not references

6a3f0b460c Blackfin arch: fix bug cplbmgr.S does not exit properly on error condition
https://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=1685

Ensure that cache/protection is turned back on when we get a
fault, and ensure that the initial population of the CPLB tables are
correct - that kernel is locked in CPLB tables

3bebca2d20 Blackfin arch: to do some consolidation of common code and common name spaces
now all BLKFIN should be BFIN, should be no functional changes.

1aafd90912 Blackfin arch: revise anomaly handling by basing things on the compiler not the kconfig defines
revise anomaly handling by basing things on the compiler not the kconfig defines,
so the header is stable and usable outside of the kernel. This also allows us to
move some code from preprocessing to compiling (gcc culls dead code)
which should help with code quality (readability, catch minor bugs, etc...).

29440a2b4c Blackfin arch: Start untangling the CPLB handling code.
- Move cache initialization to C from assembly.
 - Move anomaly workaround for writing [ID]MEM_CONTROL to assembly, so
   that we don't have to mess around with .align directives in C source.
 - Fix a bug where bfin_write_DMEM_CONTROL would write to IMEM_CONTROL
 - Break out CPLB related code from kernel/setup.c into their own file.
 - Don't define variables in header files, only declare them.
