Update the FIP image generation by adding the BL33_CFG parameter.
This is needed for the ST version of ATF.

Similarly to Uboot, this patch adds the ability to copy in and build
out-of-source device tree sources during an ATF build.

Hello,

I am just following up with these two patches, to make sure you did not forget
or miss it. Thanks.

What I don't like about this is that (for now) this BL33_CFG variable
is specific to the ST fork of TF-A. If we start adding support for all
the random variables that vendor-specific forks create, it's soon going
to be a nightmare.

Instead of this, could you try to add something like:

BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES="BL33_CFG=$(BINARIES_DIR)/your-dtb.dtb"

and see if that works ?

Best regards,

Thomas
