[U-Boot] [PATCH v2 0/9] PSCI v0.2 framework for ARMv8
Apologies for the long delay, this is v2 of the series of patches that creates a generic PSCI v0.2 framework for ARMv8.
The first 3 patches refactor existing code so that ARMv7 PSCI, ARMv8 spin-table and ARMv8 PSCI can coexist.
The 4th patch modifies the spin table implementation for the ARMv8 foundation model to create per cpu release addresses
The next 5 patches create a generic framework for PSCI v0.2 in ARMv8.
The implementation is modelled on the pre-existing PSCI v0.1 support in ARMv7.
PSCI support patches for the ARMv8 Foundation model that implement the mandatory PSCI functions and enable PCSI will follow very soon.

It's been long since Arnab posted this series.
This works fine for me on ARMv8 foundation model and also with minor modifications on Freescale's LS2085A platform.
Can this be merged to the u-boot tree or are we waiting for a v3 to be spun-out by Arnab.

Another version is required. I am working on it (very slowly, I admit).
Expect a new version this weekend.
Thanks Arnab
