OK, then we could add this to the .make file:
TF_A_MAKE_OPT := \
CROSS_COMPILE=$(BOOTLOADER_CROSS_COMPILE) \
HOSTCC=$(HOSTCC) \
PLAT=$(PTXCONF_TF_A_PLATFORM) \
ARCH=$(PTXCONF_TF_A_ARCH_STRING) \
ARM_ARCH_MAJOR=$(PTXCONF_TF_A_ARM_ARCH_MAJOR) \
BUILD_STRING=$(PTXCONF_TF_A_VERSION) \
$(call remove_quotes,$(PTXCONF_TF_A_EXTRA_ARGS)) \
all
BUILD_STRING can still be overriden in TF_A_EXTRA_ARGS if needed.
