Subject: [PATCH 0/2] Add EDAC support for Kryo CPU core caches

This series implements EDAC support for error reporting on
Kryo{3,4}XX CPU caches L1,L2, L3-SCU. All the cores(big.LITTLE)
in Kryo{3,4}XX CPUs implement RAS extensions and use interrupt
based ECC mechanism to report errors.

This series has been tested on SC7180, SDM845, SM8150 SoCs with
Kryo{3,4}XX CPU cores based on ARM Cortex-A55, Cortex-A75 and
Cortex-A76.

This implementation is platform specific in contrast to the
patch posted last time for generic error reporting on arm cortex
implementations with RAS extensions by Kyle Yan.

Downstream implementation of this can be found at:
