Hi everyone,
This series enables PSCI support for the H3. Like other Allwinner SoCs, the implementation only supports PSCI 0.1, specifically only secondary CPU boot/hotplug.
Patch 1 supports the SMTA (previously called TZPC) TrustZone hardware on H3. This controls non-secure access to some important hardware blocks.
Patch 2 supports the security switch in H3's CCU. This is H3 only. No other SoCs have this feature.
Patch 3 supports H3 using sun6i PSCI implementation. H3 uses the same power sequence as sun6i, including the power clamps. This is shown in Allwinner's SDK, and confirmed / tested by Siarhei.
Patch 4 enables PSCI support for the H3 in Kconfig.
I've only tested booting HYP/SMP on my Orange Pi PC. Hotplugging was not tested, but should work.
Many thanks for this patch-set, I've applied this to my tree, and it will be part of the pull-req I plan to send out this weekend.
Regards,
Hans
