core: ivshmem: Prepare for INTx support
Analogously to arch_ivshmem_update_msix, introduce the arch callback
arch_ivshmem_update_intx which is invoked whenever the new INTx control
register is written.
The INTx control register definition is taken from the original
revision-0 ivshmem device, though without adding the status register at
offset 4 as well. We model INTx as edge-triggered - in deviation from
the PCI spec -, so there is no reason to add such a register with all
its logic.
Furthermore, we fill the interrupt pin register in the absence of MSI-X,
using standard PCI pin rotation based on the device slot.

arm: ivshmem: Add support for INTx-based interrupt injection
Fall back to INTx in case an ivshmem device comes without MSI-X vectors.
This is now implemented for ARM, using standard PCI pin rotation based
on the device slot.
x86 has no need for INTx as MSI-X is always supported (plus there is a
less uniform legacy INTx injection path which prevents a generic
solution).

driver: Remove shared memory devices prior to disabling the hypervisor
Once the Jailhouse is disabled, there is no one handling accesses to the
virtual shared memory devices anymore. So better remove them from Linux
before the actual disabling hypercall. To remain symmetric, we also pull
adding out of jailhouse_cell_register_root.

Log Message:
-----------
driver: Register virtual PCI controller via device tree overlay
In order to add a virtual PCI host controller to the root cell after
Jailhouse activation on ARM/ARM64, we need to inject a device tree
modification. For this purpose, overlays were invented and are already
support by upstream since 3.19.
All we need to do is to fill a fragment template with some variable
parameters that can be derived from the system configuration: virtual
IRQ base, ECAM base address, and the uncached memory window size, which
can be derived from the number of ivshmem devices. We also need to
resolve the link to the GIC as the host's device tree may not have the
required symbols included.
Once the fragment is patched, we can register it, and Linux will detect
and handle the new platform device.
Note that the upstream pci-host-generic Linux driver still has issues
when it comes to unloading (and actually also rollback on errors).
Fixing this is WiP.
To use this feature with the Tegra K1, the kernel has to be patched to
allow multi-domain PCI so that a second PCI host controller can be
enabled besides the non-extensible physical controller (see
https://groups.google.com/d/msg/jailhouse-dev/5BnCAFAzykI/wHgj2UUbCwAJ).

config: Enable PCI and inter-cell communication for AMD Seattle
Describe the PCI resources of the AMD Seattle so that devices can be
reassigned.
Also add one ivshmem device for networking purposes and extend the
non-root Linux cell accordingly. We can safely expose the physical
GICv2m for this purpose, but read-only. To avoid that root and non-root
cell use the same MSI frame (which are reported by the GICv2m),
overwrite the frame parameter in the non-root cell device tree.

configs: Enable inter-cell communication for Jetson TK1
Add ivshmem devices to root cell and linux-demo for networking purposes.
A virtual PCI host is introduced and INTx SPIs are carefully selected
for both sides so that they fall into the supported set of the GICD and
do not overlap with actually used interrupts.
We need to go the vPCI path because Linux does not allow us to inject
any virtual devices into the physical bus, see also
https://www.mail-archive.com/[email protected]/msg01015.html.
To enable the second PCI host controller, multi-domain PCI support is
required for the Jetson, thus a small patch to the related Kconfig file
of the kernel.
The K1 only supports 160 SPIs, so adjust the root cell mask at this
chance as well.

x86: Only allow changes to MTRR enable bit in IA32_MTRR_DEF_TYPE
Expose the system-wide state that we inherited when starting Jailhouse
also to non-root cells and only allow modifications of the enable bit.
This ensure that non-root cells see the correct MTRR mapping, including
the proper default type. Specifically Linux may otherwise get confused
and start to map the shared memory regions as uncacheable - obviously
reducing the inter-cell communication performance.
