[PATCH v3 0/3] pnv nest1 chiplet model

[Chalapathi V]

Hello,

For modularity reasons the P10 processor chip is split into multiple
chiplets individually controlled and managed by the pervasive logic.
The boundaries of these chiplets are defined based on physical design
parameters like clock grids, the nature of the functional units as well
as their pervasive requirements (e.g. clock domains). Examples of chiplet
in the P10 chip are processor cores and caches, memory controllers or IO
interfaces like PCIe. Partitioning the processor chip into these chiplets
allows the pervasive logic to test, initialize, control and manage these
chip partitions individually.

In this series, we create a nest1 chiplet model and implements the chiplet
control scom registers on nest1 chiplet. The chiplet control registers does
the initialization and configuration of a chiplet.

In this PATCH Cedric's review comments has been addressed to add a new QOM
model for pervasive chiplet and initialize and realize in nest1 chiplet model.

/nest1_chiplet (pnv-nest1-chiplet)
      /perv_chiplet (pnv-pervasive-chiplet)
        /xscom-chiplet-control-regs[0] (memory-region)
