0a99061426 Blackfin: fix length checking in kgdb_ebin2mem
The kgdb_ebin2mem() was decrementing the count variable to do parsing, but
then later still tries to use it based on its original meaning.  So leave
it untouched and use a different variable to walk the memory.

11aca0e735 Blackfin: kgdb: fix up error return values
The Blackfin kgdb code was all passing back positive errno values when it
really should have been using negative errno values.

8a0e9acfd1 Blackfin arch: Fix bug - hardware breakpoint doesn't always work in kgdb
Hardware breakpoint doesn't always work in kgdb. It works at the first
two times, but if you repeatedly trigger that hardware breakpoint, it
would slip over that point once in two times.

Fix it by always setting hw bp skip to 0. gdb does skip after hw bp trap.

0d1cdd7ab6 Blackfin arch: Fix bug - skip single step in high priority interrupt handler instead of disabling all interrupts in single step debugging.
Skip single step if event priority of current instruction is higher than
that of the first instruction, from which gdb starts single step.
