From: Krishna Gudipati <kgudipat@xxxxxxxxxxx>
Change details:
- This patch is part of the BFA cleanup.
- Cleaning up BFAD releated code:
bfad_intr.c, bfad_fwimg.c will be merged to bfad.c
- Removing bfad.c first to make sure the review is easier.
- Removing unused bfad_os.c
Signed-off-by: Krishna Gudipati <kgudipat@xxxxxxxxxxx>
