Hello Sudeep,
In case it helps. I have successfully tested the 7 patches series
on some platforms, playing a bit with few configurations.
Qemu emulator for arm64/cortex-a57 with TF-A (v2.x) as secure firmware.
Qemu emulator for arm/cortex-a15. OP-TEE (v3.x) as secure firmware.
A stm32mp15 device (arm/cortex-a7), tested both TF-A (v2.x) and
OP-TEE (3.7.0, 3.9.0-rc) as runtime secure firmware.
Helper functions arm_smccc_1_1_get_conduit()/arm_smccc_1_1_invoke()
works as expected AFAICT. No regression seen with older secure
firmwares.
For the patches 1 to 6, as I poorly tested [v3,7/7] soc ids,
based on tag next-20200505 [1]:
