Cover letter [U-Boot] [PATCH 0/8] PSCI v0.2 framework for ARMv8
Quoted 5 lines · Arnab Basu

This series of patches 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.

Quoted 7 lines

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 will follow shortly.

I forgot to mention that this patch set requires the following patches:
