, defining macro CONFIG_FSL_SMP_RELEASE_ALL will use
the CPU_RELEASE_ADDR. Spin table and the boot page is reserved in
device tree so OS won't overwrite.

-existing PSCI v0.1 support
in ARMv7.
PSCI support patches for the ARMv8 Foundation model will follow shortly.
Arnab Basu (8):
ARM: PSCI: Update psci.h for psci v0.2
ARM: PSCI: Alow arch specific DT patching
ARMv8/fsl-lsch3: Refactor spin-table code
ARMv8: PSCI: Add linker section to hold PSCI
This creates the function cpu_update_dt for ARMv8 which currently patches
the cpu node in the device table and sets enable-method to spin-table.

Both ARMv7 and ARMv8 need to patch the device tree but the kind
of patching done is different. This creates a function that can be
defined by each architecture to handle the differences

Implement core support for PSCI. As this is generic code, it doesn't
implement anything really useful (all the functions are returning

This is largely ported from the similar code that exists for ARMv7

A separate linker section makes it possible to keep this code either

So far no one is using this section.

This series of patches creates a generic PSCI v0.2 framework for ARMv8.
The first 3 patches refactor existing code so that ARMv7 PSCI,
