[U-Boot] State of ARMv7 PSCI support?

Folks,

I am curious about the state of the PSCI support on ARMv7, specifically the Cortex-A9, these days. I see that Marc Zyngier posted a 9 part patch a few months ago:

[PATCH 0/9] ARMv7: add PSCI support to u-boot

And I see that aspects of that series (Patch 1 Fix alignment requirements for vectors) have otherwise gone into mainline, but I was wondering if a rebased and more recent version of the patch series was available?

I checked the ARM repo, and I can't find the series in there either. Is there a plan or interest in seeing this support added still?

Thanks, jdl
