Hi Varun,
Please consider Ivy (and Quark) payloads are remnant from older SPCI specs and must be considered deprecated. We did not clean this in deep to remove the related test code but AFAIK it's just not used anywhere in the test suites (although it may still be built). We may have a plan to upgrade this later when working on S-EL0 partitions on top of Hafnium, but that's not an immediate priority.
Considering Cactus, that's the bare-metal S-EL1 payload you can use in place of a real TOS on top of Hafnium. The intent is to test FF-A ABIs unitarily at secure virtual FF-A instance. TFTF at EL2 exercises the ABI at non-secure physical FF-A instance to communicate with the secure endpoint.
See below the build commands we use for FVP. Hopefully this should help porting to your platform. Notice it needs as well building the SPMC (aka Hafnium in the secure side), which only supports FVP at this moment (and Rpi, qemu...) It's not described here but I can guide you through this as well. I think you can just use a dummy BL32 payload for now, at least to test the build/integration.
If TFTF and TF-A reside in the same top level dir:
TFTF: this builds TFTF and cactus secure partitions make CROSS_COMPILE=aarch64-none-elf- PLAT=fvp TESTS=spm -j8
TF-A: this uses TFTF, and assembles two cactus secure partitions within the FIP make \ CROSS_COMPILE=aarch64-none-elf- \ SPD=spmd \ CTX_INCLUDE_EL2_REGS=1 \ ARM_ARCH_MINOR=4 \ BL33=../tf-a-tests/build/fvp/debug/tftf.bin \ BL32=<path-to-secure-hafnium-bin>/hafnium.bin \ SP_LAYOUT_FILE=../tf-a-tests/build/fvp/debug/sp_layout.json \ PLAT=fvp \ all fip
The tool last FIP tool entries are the two cactus instances: B4B5671E-4A90-4FE1-B81F-FB13DAE1DACB: offset=0x47DA3, size=0xC168, cmdline="--blob" D1582309-F023-47B9-827C-4464F5578FC8: offset=0x53F0B, size=0xC168, cmdline="--blob"
Regards, Olivier.

Hello,
In order to test the SPM dispatcher from TF-A, we plan to enable ‘cactus’ and ‘ivy’ on Tegra194 platforms. I was able to muscle my way through all the compilation issues, but the final payload generation part is not that clear.
Can someone please help me with the steps to generate the final FIP package with all the payloads – TF-A, Cactus, Ivy?
Thanks.
