The whole point of Buildroot is to automate the build process, so this should be done by a Buildroot package, rather than manually by the user. So a package for ATF should probably be created.
I also work on an ARM64 platform that uses ATF+U-Boot, so I'll be able to compare and tell you whether what you're proposing is only applicable to Juno, or can be used for other platforms as well.

Using the legacy build system with a modern U-Boot such as 2016.03 doesn't make much sense. Please use the kconfig based build system, unless there is a real reason not to.

It would great to do it 100% automatic. I'll be waiting for your feedback regarding your ARM64 platform. If it is the same we could do it together.

Well, the build process is quite similar. I build ATF with:
make CROSS_COMPILE=aarch64-linux-gnu- BL33=/path/to/uboot USE_COHERENT_MEM=0 PLAT=<platform> DEBUG=1 LOG_LEVEL=20 all fip
I think DEBUG=1 and LOG_LEVEL=20 are not important, but I think the PLAT= and USE_COHERENT_MEM= variables are important in my case.
So I guess you do do something like:
make CROSS_COMPILE=$(TARGET_CROSS) \ BL33=$(call qstrip,$(BR2_BOOT_ATF_PAYLOAD_PATH) \ $(BR2_BOOT_ATF_ADDITIONAL_VARIABLES) \ all fip
and that's it. Of course, the location from where you download ATF should be configurable, because I'm not using the ATF from ARM directly, but a vendor-specific fork.
Thanks!

PATCH 1/1 uboot build and deploy added to juno board
Hi Thomas,
I developed the atfirmware config and I am having problems in the Makefile. How does the buildroot structure git clones / untar / etc.? I suppose there is a common spot to do these stuff right?
Send in attchment tarball of the new package. I am thinking of adding it to Bootloaders. What do you think?
Thanks.

Hello,

I developed the atfirmware config and I am having problems in the
Makefile. How does the buildroot structure git clones / untar / etc.? I suppose there is a common spot to do these stuff right?
Look at how the barebox build is done, boot/barebox/barebox.mk.

Well, your .mk file has no chance to work, you're not even calling any Buildroot package infrastructure, your build commands are not inside a variable, etc.
Quoted 1 line
I am thinking of adding it to Bootloaders. What do you think?
Yes, it should obviously go in the Bootloaders menu.
Thanks!
