[PATCH v2 0/3] Retrieve System Cache Table (SCT) descriptors from a shared memory region.

[Francisco Munoz Ruiz]

On newer Qualcomm platforms, SCT initialization and programming are
handled entirely by firmware outside of Linux. The kernel is expected
to consume the pre-initialized descriptor data rather than configure
the SCT itself. The LLCC driver therefore only needs to locate and
parse the descriptor table provided by firmware.

This change implements support for this mechanism in the llcc-qcom
driver, enabling SCT consumption on platforms that expose SCT
programming through firmware. The existing behavior for SoCs where
the kernel programs SCT directly remains unchanged.
