Liang Yi 688a41c290 hv: mod: do not use explicit arch name when including headers
Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".

In other words, we are adopting the same practice in Linux kernel.

Victor Sun 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;

Li Fei1 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.

Yin Fengwei 68269a559f gpa2hva: add INVAVLID_HPA return value check
For return value of local_gpa2hpa, either INVALID_HPA or NULL
means the EPT walking failure. Current code only take care of
NULL return and leave INVALID_HPA as correct case.

In some cases (if guest page table is filled with invalid memory
address), it could crash ACRN from guest.

Add INVALID_HPA return check as well.
Also add @pre assumptions for some gpa2hpa usages.

Li Fei1 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.

dongshen 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
