TF-A (Trusted Firmware-A) == ATF (Arm Trusted Firmware) For seam reasom ARM, eh I mean arm, decided to rebrand it. > $ make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31 > make -C plat/rockchip/rk3399/drivers/m0 > BUILD=/root/arm-trusted-firmware/build/rk3399/release/m0 > make[1]: Entering directory > '/root/arm-trusted-firmware/plat/rockchip/rk3399/drivers/m0' > CC src/dram.c > arm-none-eabi-gcc -g -mcpu=cortex-m0 -mthumb -Wall -O3 -nostdlib > -mfloat-abi=soft -ffunction-sections -fdata-sections > -fomit-frame-pointer -fno-common -Iinclude/ -I../../include/shared/ > -MMD -MT /root/arm-trusted-firmware/build/rk3399/release/m0/dram.o -c > src/dram.c -o /root/arm-trusted-firmware/build/rk3399/release/m0/dram.o > make[1]: arm-none-eabi-gcc: Command not found The RK3399 has a Cortex-M0 MCU built into it, and TF-A includes a firmware for that. I think it is supposed to assist the SoC with suspend/resume. You'll need to install an arm-none-eabi- cross compiler as well to build it.
