Lucas Mateus Castro (alqotel) 962104f044 hw/ppc: moved hcalls that depend on softmmu
The hypercalls h_enter, h_remove, h_bulk_remove, h_protect, and h_read,
have been moved to spapr_softmmu.c with the functions they depend on. The
functions is_ram_address and push_sregs_to_kvm_pr are not static anymore
as functions on both spapr_hcall.c and spapr_softmmu.c depend on them.
The hypercalls h_resize_hpt_prepare and h_resize_hpt_commit have been
divided, the KVM part stayed in spapr_hcall.c while the softmmu part
was moved to spapr_softmmu.c

BALATON Zoltan ba7e5ac18e hw/ppc: Add emulation of Genesi/bPlan Pegasos II
Add new machine called pegasos2 emulating the Genesi/bPlan Pegasos II,
a PowerPC board based on the Marvell MV64361 system controller and the
VIA VT8231 integrated south bridge/superio chips. It can run Linux,
AmigaOS and a wide range of MorphOS versions. Currently a firmware ROM
image is needed to boot and only MorphOS has a video driver to produce
graphics output. Linux could work too but distros that supported this
machine don't include usual video drivers so those only run with
serial console for now.

David Gibson 6c8ebe30ea spapr: Add PEF based confidential guest support
Some upcoming POWER machines have a system called PEF (Protected
Execution Facility) which uses a small ultravisor to allow guests to
run in a way that they can't be eavesdropped by the hypervisor.  The
effect is roughly similar to AMD SEV, although the mechanisms are
quite different.

Most of the work of this is done between the guest, KVM and the
ultravisor, with little need for involvement by qemu.  However qemu
does need to tell KVM to allow secure VMs.

Because the availability of secure mode is a guest visible difference
which depends on having the right hardware and firmware, we don't
enable this by default.  In order to run a secure guest you need to
create a "pef-guest" object and set the confidential-guest-support
property to point to it.

Note that this just *allows* secure guests, the architecture of PEF is
such that the guest still needs to talk to the ultravisor to enter
secure mode.  Qemu has no direct way of knowing if the guest is in
secure mode, and certainly can't know until well after machine
creation time.

To start a PEF-capable guest, use the command line options:
    -object pef-guest,id=pef0 -machine confidential-guest-support=pef0

Daniel Henrique Barboza 1eee995026 ppc: introducing spapr_numa.c NUMA code helper
We're going to make changes in how spapr handles all
ibm,associativity* related properties to enhance our current NUMA
support.

At this moment we have associativity code scattered all around
spapr_* files, with hardcoded values and array sizes. This
makes it harder to change any NUMA specific parameters in
the future. Having everything in the same place allows not
only for easier tuning, but also easier understanding since all
NUMA related code is on the same file.

This patch introduces a new file to gather all NUMA/associativity
handling code in spapr, spapr_numa.c. To get things started, let's
remove associativity-reference-points and max-associativity-domains
code from spapr_dt_rtas() to a new helper called spapr_numa_write_rtas_dt().
This will decouple spapr_dt_rtas() from the NUMA changes that
are going to happen in those two properties.

Marc-André Lureau 2c44220d05 meson: convert hw/arch*
Each architecture's sourceset is placed in an hw_arch dictionary, and picked up
from there when building the per-emulator static_library.
