[U-Boot] [RESEND PATCH] rockchip: reserve memory for rk3399 ATF data
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.
More detail about cortex-M0 code in ATF: https://github.com/ARM-software/arm-trusted-firmware/commit/ 8382e17c4c6bffd15119dfce1ee4372e3c1a7890
