Hello 166291,
I was struggling with the ATF long into the night when I stumbled upon this post. I had made the same changes as you but on the ST ATF repo and got the following.
NOTICE: CPU: STM32MP157CAC Rev.B
NOTICE: Model: STMicroelectronics STM32MP157C-DK2 Discovery Board
INFO: Reset reason (0x15):

I figued I would give your repo a run and see if that works, but I end up with this
NOTICE: CPU: STM32MP157CAC Rev.B

I feel lost. Any ideas what I could be missing?
I am building with gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf and the string
make -C ${<your ATF repo cleaned with said branch checked out>} CROSS_COMPILE=${<as above>} PLAT=stm32mp1 LOG_LEVEL=40 DTB_FILE_NAME=stm32mp157c-dk2.dtb ARM_ARCH_MAJOR=7 ARCH=aarch32 AARCH32_SP=sp_min STM32MP_USB_PROGRAMMER=1 STM32MP_EMMC=1 STM32MP_SDMMC=1 all
I load the code with STM32CubeProgrammer/bin/STM32_Programmer_CLI -c port=usb1 -w flash.tsv

Last. Great thanks for the info in your post!
