There are 3 region used by rk3399 ATF: - bl31 code, locate at 0x10000; - cortex-m0 code and data, locate at 0xff8c0000; - bl31 data, locate at 0xff8c1000 ~ 0xff8c4000; SPL_TEXT_BASE starts from 0xff8c2000, we need to reserve memory for ATF data, or else there will have memory corrupt after SPL load ATF image.
