Yes. I have only tried upstream TF-A though.

OSELAS.Toolchain-2019.09.1

But I think you are calling it with the wrong parameters, you need:

make ARCH=aarch32 ARM_ARCH_MAJOR=7 AARCH32_SP=sp_min DEBUG=1 STM32MP_EMMC=1 \
        DTB_FILE_NAME=stm32mp157c-dk2.dtb \
        CROSS_COMPILE=${CROSS_COMPILE} \
        PLAT=stm32mp

It's described in the TF-A platform documentation.
You can also check out the ptxdist rule for building it:

Cheers,
Ahmad
