Yes, they are mutually exclusive, and may I prepare defconfigs like
these:
 abiv1_defconfig
 abiv2_defconfig (ck807 ck810 ck860 are also mutually exclusive in
 -mcpu=ck807/ck810/ck860, you need "make menuconfig" to select correct CPU,
 so they couldn't be determined from DT. just like ARMv5, ARMv7-A and 
 ARMv7-M)

Ok, I'll clean them up in next version patch.

Thx for the tip.
