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).

460124f984 dm: e820: refine e820 layout
We don't reserve PCI MMIO in e820 Table, it's included in DSDT ACPI Table.
About 0xA0000 - 0x100000 entry, we don't have any ACPI Table touch this region.
So we could remove it too.

After this change, we could only pass the reserved e820 table which we must
reserve to OVMF. In this case, the OVMF could trust ACRN-DM and pass the
reserved e820 table to guest instead of dropping it.

This patch needs the corresponding modify in OVMF. Otherwise, the guest could
not boot.

89908bf510 dm:gvt:update gvt bars before other pci devices write bar address
The current design has the following problem:
uos kernel may update gvt bars' regions,
but ACRN-DM doesn't know this update.
ACRN-DM only know out-of-date gvt bar regions,
For simplicity, mark these bar regions as OOD bar regions.
uos kernel may allocate OOD bar regions for
other pci devices, which will result in ACRN-DM
bar regions inconsistency with uos kernel.

The new design is the following:
When other pci device update bar regions
(1) ACRN-DM updates gvt bars' regions
provided by a system file.
(2) ACRN-DM updates this pci device bar regions

v5 -> v6:
	* add more comments

v4 -> v5:
	* remove & for callback func assignment

v3 -> v4:
	* compare gpu bar address to avoid unnecessary
	* unregistered/registered operation

v2 -> v3:
	* call unregister_bar and register_bar when update gvt bars
	* update gvt reserved regions when update gvt bars

f27d47542a dm:gvt:adjust pci bar region with reserved bar regions
ACRN-DM has reserved gvt bar regions.

This patch ensures other pci devices' bar regions
won't overlap with reserved bar regions.

v6 -> v7:
	* rename some struct and func

v5 -> v6:
	* remove outdated comment
	* add comments for code reading
	* code cleaning about gvt bar0 and bar2 size

v4 -> v5:
	* rename adjust_bar_region and adjust_bar_region_by_gvt_bars
	* change adjust_bar_region_by_gvt_bars interface for code cleaning

v3 -> v4:
	* add static struct gvt_region  instead of definition or pointer array.

v2 -> v3:
	* repalce pci_emul_alloc_bar with gvt_reserve_resource when allocate gvt bars
	* use register_bar to detect if gvt bars confilts with pci devices

v1 -> v2:
	* don't limit the gvt bar type is MEM32 when deal with pci bar
	* add is_two_region_overlap func to detect if two regions overlap
	* add region array to store gvt bar0 and bar2 regions

1ac0b57c6a dm:gvt:reserve gvt bar regions in ACRN-DM
The current design has the following problem:
gvt uses some pci bar regions,
but ACRN-DM isn't aware of these regions.
So ACRN-DM may allocate these regions for other pci devices,
which will result in other pci devices bar regions
overlap with gvt bar regions.

The new design is the following:
(1) ACRN-DM reads gvt bar regions
which are provided by physical gpu;
(2) ACRN-DM reserves gvt bar regions

v6 -> v7:
	* use array to store reserved bar regions
	* rename some struct and func

v5 -> v6:
	* rename enable_gvt to gvt_enabled
	* add a interface to reserve bar regions
	* reserve gvt bar regions

7ef9498fe0 acrn/dm: gvt returns negative errno to terminate the initialization
When the "i915.enable_gvt=0" is added for SOS kernel boot args, ACRN-DM will
fail in course of gvt initialization and errno is returned directly.
As the errno defined in linux/errno.h is positive, it will continue
the unexpected initialization in ACRN-DM and then the segment fault is
triggered.
So negative errno is returned in order to terminate the initialization.
