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).

98c80d75b8 hv: dm: Use new virtual device management ioctls
IC_ADD_HV_VDEV		->	ACRN_IOCTL_CREATE_VDEV
IC_REMOVE_HV_VDEV	->	ACRN_IOCTL_DESTROY_VDEV
struct acrn_emul_dev	->	struct acrn_vdev

Also, move struct acrn_vdev to acrn_common.h as this structure is used
by both DM and HV.

996e8f680c HV: pci-vuart support create vdev hcall
Add cteate method for vmcs9900 vdev in hypercalls.

The destroy method of ivshmem is also suitable for other emulated vdev,
move it into hcall_destroy_vdev() for all emulated vdevs

691abe90ff HV: vuart: send msi for pci vuart type
if vuart type is pci-vuart, then use MSI interrupt

split vuart_toggle_intr() control flow into vuart_trigger_level_intr() &
trigger_vmcs9900_msix(), because MSI is edge triggered, no deassertion
operation. Only trigger MSI for pci-vuart when assert interrupt.

55b7fae67a HV: pci-vuart: pci based vuart emulation
Add emulation for pci based vuart device mcs9900 at hv land.
add struct pci_vdev_ops vuart_pci_ops, the vdev callbalks for vuart.

How to use
In misc/vm_configs/scenarios/<SCENARIO>/<BOARD>/pci_dev.c, add pci
vuart config to vm_pci_devs[] array. For example:

struct acrn_vm_pci_dev_config vm0_pci_devs[] = {
       /* console vuart setting*/
       {
               .emu_type = PCI_DEV_TYPE_HVEMUL,
               .vbdf.bits = {.b = 0x00U, .d = 0x04U, .f = 0x00U},
               .vdev_ops = &vmcs_ops,
               .vbar_base[0] = 0x80001000,	/* mmio bar */
               .vbar_base[1] = 0x80002000,	/* msix bar */
               .vuart_idx = 0,
       },
       /* communication vuart setting */
       {
               .emu_type = PCI_DEV_TYPE_HVEMUL,
               .vbdf.bits = {.b = 0x00U, .d = 0x05U, .f = 0x00U},
               .vdev_ops = &vmcs_ops,
               .vbar_base[0] = 0x80003000,
               .vbar_base[1] = 0x80004000,
               .vuart_idx = 1,
               .t_vuart.vm_id = 1U,
               .t_vuart.vuart_id = 1U,
       },
}
