a705ff2dac hv: relocate ACPI DATA address to 0x7fe00000
Relocate ACPI address to 0x7fe00000 and ACPI NVS to 0x7ff00000 correspondingly.
In this case, we could include TPM event log region [0x7ffb0000, 0x80000000)
into ACPI NVS.

5ecca6b256 HV: vpci: check if address is in VM BAR MMIO space
When guest doing BAR re-programming, we should check whether
the base address of the BAR is valid.This patch does this check by:
1. whether the gpa is located in the responding MMIO window
2. whether the gpa is aligned with the BAR size

a2fd8c5a9d pci: mcfg: limit device bus numbers which could access by ECAM
Per PCI Firmware Specification Revision 3.0, 4.1.2. MCFG Table Description:
Memory Mapped Enhanced Configuration Space Base Address Allocation Structure
assign the Start Bus Number and the End Bus Number which could decoded by the
Host Bridge. We should not access the PCI device which bus number outside of
the range of [Start Bus Number, End Bus Number).
For ACRN,  we should:
1. Don't detect PCI device which bus number outside the range of
[Start Bus Number, End Bus Number) of MCFG ACPI Table.
2. Only trap the ECAM MMIO size: [MMCFG_BASE_ADDRESS, MMCFG_BASE_ADDRESS +
(End Bus Number - Start Bus Number + 1) * 0x100000) for SOS.

34547e1e19 HV: add acpi module support for pre-launched VM
Previously we use a pre-defined structure as vACPI table for pre-launched
VM, the structure is initialized by HV code. Now change the method to use a
pre-loaded multiboot module instead. The module file will be generated by
acrn-config tool and loaded to GPA 0x7ff00000, a hardcoded RSDP table at
GPA 0x000f2400 will point to the XSDT table which at GPA 0x7ff00080;

da81a0041d HV: add e820 ACPI entry for pre-launched VM
Previously the ACPI table was stored in F segment which might not be big
enough for a customized ACPI table, hence reserve 1MB space in pre-launched
VM e820 table to store the ACPI related data:

	0x7ff00000 ~ 0x7ffeffff : ACPI Reclaim memory
	0x7fff0000 ~ 0x7fffffff : ACPI NVS memory

1859727abc hv: vapci: add tpm2 support for pre-launched vm
On WHL platform, we need to pass through TPM to Secure pre-launched VM. In order
to do this, we need to add TPM2 ACPI Table and add TPM DSDT ACPI table to include
the _CRS.

Now we only support the TPM 2.0 device (TPM 1.2 device is not support). Besides,
the TPM must use Start Method 7 (Uses the Command Response Buffer Interface)
to notify the TPM 2.0 device that a command is available for processing.

4eb3f5a0c7 hv: vacpi: add fadt table support
Add FADT table support to support guest S5 setting.

According to ACPI 6.3 Spec, OSPM must ignored the DSDT and FACS fields if them're zero.
However, Linux kernel seems not to abide by the protocol, it will check DSDT still.
So add an empty DSDT to meet it.

b447ce3d86 hv: add ACPI support for pre-launched VMs
Statically define the per vm RSDP/XSDT/MADT ACPI template tables in vacpi.c,
RSDP/XSDT tables are copied to guest physical memory after checksum is
calculated. For MADT table, first fix up process id/lapic id in its lapic
subtable, then the MADT table's checksum is calculated before it is copies to
guest physical memory.

Add 8-bit checksum function in util.h
