There are 3 regions used by rk3399 ATF:

bl31 code, located at 0x10000;
cortex-m0 code and data, located at 0xff8c0000;
bl31 data, located at 0xff8c1000 ~ 0xff8c4000;

SPL_TEXT_BASE starts from 0xff8c2000, we need to reserve memory
for ATF data, or else there will be memory corrupt after SPL
loads the ATF image.
More detail about cortex-M0 code in ATF:
