I am working on rcar gen 3 platform from Renesas and particularly on arm-trusted-firmware level.
1. bootparam_sa0.srec Loader(Boot parameter) <======= arm-trusted-firmware
2. bl2-m3ulcb.srec Loader <======= arm-trusted-firmware
3. cert_header_sa6.srec Loader(Certification) <======= arm-trusted-firmware
4. bl31-m3ulcb.srec ARM Trusted Firmware <======= arm-trusted-firmware
5. tee-m3ulcb.srec Open Portable Trusted OS <======= optee-os
6. u-boot-elf.srec U-Boot <======= u-boot
I built BL31 by command with Gcc v5.4
$ make ARCH=aarch64 CROSS_COMPILE=aarch64-linux-gnu- PLAT=rcar LSI=M3 RCAR_GEN3_ULCB=1 RCAR_LOSSY_ENABLE=1 RCAR_DRAM_SPLIT=2 PMIC_LEVEL_MODE=0 bl31
But I ran into the below err:

Same error: https://github.com/ARM-software/tf-issues/issues/417
The assembly code is correct and is apparently not the problem.
It seemed that it depends on Compiler. I was trying to install gcc/g++ 7.4 cross:
on Ubuntu 16.04, and modified the Makefile to used gcc-7 (cross), g++-7 (cross), but still had this error. How can I overcome this err ?
