Thanks for comment.
In glibc and linux we only cares about following cpu and extensions. 

    ck610 only  have: ck610
    ck807 could have: ck807 ck807f ck807vf ck807ef
    ck810 could have: ck810 ck810f ck810vf ck810ef
    ck860 could have: ck860 ck860f ck860vf
  f: means FPU co-processor
  v: means VDSP co-processor just like "ARM-NEON"
  e: is our old DSP co-processor which use HI-LO regs for operation. In
  current ck807/ck810 they default have HI-LO regs.
 
For this patch-set, we support:
   ck610
  (ck807/ck807f/ck807ef)
  (ck810/ck810e/ck810ef)

ck6** use csky-*-linux-gnuabiv1, ck8** use csky-*-linux-gnuabiv2
I will update the introduction for these.
 
It seems only this need be added to the README file. Is that correct?
        csky-*-linux-gnuabi
