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) > It looks like you still have lots of options enabled that I wouldn't > expect you to need.

Thx for the tip. Guo Ren
