2025-02-14soc: qcom: Do not expose internal servreg_location_entry_ei arrayKrzysztof Kozlowski
'struct qmi_elem_info servreg_location_entry_ei' is used only internally in qcom_pdr_msg.c, so drop the extern declaration to make headers smaller and code more obvious about intention.

2024-06-24soc: qcom: add pd-mapper implementationDmitry Baryshkov
Existing userspace protection domain mapper implementation has several issue. It doesn't play well with CONFIG_EXTRA_FIRMWARE, it doesn't reread JSON files if firmware location is changed (or if firmware was not available at the time pd-mapper was started but the corresponding directory is mounted later), etc. Provide in-kernel service implementing protection domain mapping required to work with several services, which are provided by the DSP firmware. This module is loaded automatically by the remoteproc drivers when necessary via the symbol dependency. It uses a root node to match a protection domains map for a particular board. It is not possible to implement it as a 'driver' as there is no corresponding device.

2024-06-23soc: qcom: pdr: extract PDR message marshalling dataDmitry Baryshkov
The in-kernel PD mapper is going to use same message structures as the QCOM_PDR_HELPERS module. Extract message marshalling data to separate module that can be used by both PDR helpers and by PD mapper.
