Blackfin arch: merge adeos blackfin part to arch/blackfin/
[Mike Frysinger <vapier.adi@gmail.com>: - handle bf531/bf532/bf534/bf536 variants in ipipe.h - cleanup IPIPE logic for bfin_set_irq_handler() - cleanup ipipe asm code a bit and add missing ENDPROC() - simplify IPIPE code in trap_c - unify some of the IPIPE code and fix style - simplify DO_IRQ_L1 handling with ipipe code - revert IRQ_SW_INT# addition from ipipe merge - remove duplicate get_{c,s}clk() prototypes ] Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
