Zhiqiang,

After you move the macro to Kconfig, you should remove it from 
scripts/config_whitelist.txt.

Please help me understand when and where ARMV8_SEC_FIRMWARE_SUPPORT is 
turned on? I am trying to resolve the conflict between this set and 
Prabhakar's patch for LS1012A PPA http://patchwork.ozlabs.org/patch/709650/.
