Fei Li 5130dfe08b hv: vSRIOV: add VF BARs mapping for PF
When enabling SRIOV capability for a PF in Service VM, ACRN Hypervisor
should add VF BARs mapping for PF since PF's firmware would access these
BARs to do initialization for VFs when it's first created.

Geoffroy Van Cutsem 8b16be9185 Remove "All rights reserved" string headers
Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

Junjie Mao 83a938bae6 HV: treewide: fix violations of coding guideline C-TY-27 & C-TY-28
The coding guideline rules C-TY-27 and C-TY-28, combined, requires that
assignment and arithmetic operations shall be applied only on operands of the
same kind. This patch either adds explicit type casts or adjust types of
variables to align the types of operands.

The only semantic change introduced by this patch is the promotion of the
second argument of set_vmcs_bit() and clear_vmcs_bit() to
uint64_t (formerly uint32_t). This avoids clear_vmcs_bit() to accidentally
clears the upper 32 bits of the requested VMCS field.

Other than that, this patch has no semantic change. Specifically this patch
is not meant to fix buggy narrowing operations, only to make these
operations explicit.

Tao Yuhong 50d8525618 HV: deny HV owned PCI bar access from SOS
This patch denies Service VM the access permission to device resources
owned by hypervisor.
HV may own these devices: (1) debug uart pci device for debug version
(2) type 1 pci device if have pre-launched VMs.
Current implementation exposes the mmio/pio resource of HV owned devices
to SOS, should remove them from SOS.

Li Fei1 15e3062631 hv: vpci: remove is_own_device()
Now we could know a device status by 'user' filed, like

---------------------------------------------------------------------------
           | NULL              | == vdev           | != NULL && != vdev
vdev->user | device is de-init | used by itself VM | assigned to another VM
---------------------------------------------------------------------------

So we don't need to modify 'vpci' field accordingly.

Yuan Liu 9375c634dc hv: unmap SR-IOV VF MMIO when the VF physical device is disabled
To avoid information leakage, we need to ensure that the device is
inaccessble when it does not exist.

For SR-IOV disabled VF device, we have the following operations.
    1. The configuration space accessing will get 0xFFFFFFFF as a
       return value after set the device state to zombie.
    2. The BAR MMIO EPT mapping are removed, the accesssing causes
       EPT violation.
    3. The device will be detached from IOMMU.
    4. The IRQ pin and vector are released.

through the vbars instead multiple accessing of the PF VF_BAR registers.
