Gabriel Somlo 2425674438 OvmfPkg/SMBIOS: Provide default Type 0 (BIOS Information) structure
Insert a default, OVMF-specific Type 0 (BIOS Information) structure
into the SMBIOS table, unless the underlying guest VM supplies its
own, overriding instance.

As an example, QEMU, while allowing the user to specifically force
generation of a Type 0 structure, will not generate one by default,
considering that task to be the responsibility of the BIOS itself.

Based on an earlier out-of-tree patch by Laszlo Ersek <lersek@redhat.com>

Gabriel Somlo a145e28dec OvmfPkg/SMBIOS: Add QEMU support to OVMF SMBIOS driver
Locate QEMU SMBIOS data in fw_cfg and install it via the
SMBIOS protocol.

Starting with qemu-2.1, on pc/x86 machines of type >= 2.1, full
SMBIOS tables are generated and inserted into fw_cfg (i.e., no
per-field patching of locally generated structures is required).

Aside from new code to extract a SMBIOS blob from fw_cfg, this
patch utilizes the pre-existing infrastructure (already used by
Xen) to handle final SMBIOS table creation.

Gabriel Somlo 6b23d767f6 OvmfPkg/SMBIOS: Reuse handles supplied by underlying VM
The SMBIOS specification requires some structure types to
contain reference fields to other structures' handles. When
InstallAllStructures() rebuilds the SMBIOS tables by traversing
an existing source table, the use of SMBIOS_HANDLE_PI_RESERVED
causes automatically generated, arbitrary handle numbers to be
assigned to each cloned structure. This causes all reference
handle fields to become invalid.

This patch modifies InstallAllStructures() to reuse the original
handle numbers supplied by the underlying VM, preserving the
correctness of any included handle references.

lzeng14 b0a2498d34 According to PI errata 0000654 and 000811, we need use 0xFFFE to instead of 0 for EFI_SMBIOS_PROTOCOL.Add() SmbiosHandle parameter to assign a unique handle to the SMBIOS record, and for EFI_SMBIOS_PROTOCOL.GetNext() SmbiosHandle parameter to get the first matched SMBIOS handle or indicate no more SMBIOS record.
