Yi Li 6a01f23033 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
