The default PCI mmcfg base is stored in ACPI MCFG table, when
CONFIG_ACPI_PARSE_ENABLED is set, acpi_fixup() function will
parse and fix up the platform mmcfg base in ACRN boot stage;
when it is not set, platform mmcfg base will be initialized to
DEFAULT_PCI_MMCFG_BASE which generated by acrn-config tool;
Please note we will not support platform which has multiple PCI

Currently when get_rsdp is called, the EFI depriv_boot env is not initialized.
In such case it will fallback to the legacy mechanism of ACPI table.
If the ACPI table based on legacy mechanism is not found, it will fail to get
the ACPI table and then the system will hang.
On the old platform it still can parse the ACPI table from legacy mechanism.
In fact when EFI RSDP exists, the EFI RSDP is preferred instead of legacy ACPI
RSDP.
In order to avoid multiple calling of depriv_init_boot, the init_boot_operations
is renamed and called after X2apic is enabled(early_init_lapic).

now only SOS need decide boot with de-privilege or direct boot mode, while
for other pre-launched VMs, they should use direct boot mode.
this patch merge boot/guest/direct_boot_info.c &
boot/guest/deprivilege_boot_info.c into boot/guest/vboot_info.c,
and change init_direct_vboot_info() function name to init_general_vm_boot_info().
in init_vm_boot_info(), depend on get_sos_boot_mode(), SOS may choose to init
vm boot info by setting the vm_sw_loader to deprivilege specific one; for SOS
using DIRECT_BOOT_MODE and all other VMS, they will use general_sw_loader as
vm_sw_loader and go through init_general_vm_boot_info() for virtual boot vm
info filling.
this patch also move spurious handler initilization for de-privilege mode from
boot/guest/deprivilege_boot.c to boot/guest/vboot_info.c, and just set it in
deprivilege sw_loader before irq enabling.

currently, ACRN hypervisor can either boot from sbl/abl or uefi, that's
why we have different firmware method under bsp & boot dirs.
but the fact is that we actually have two different operations based on
different guest boot mode:
1. de-privilege-boot: ACRN hypervisor will boot VM0 in the same context as
native(before entering hypervisor) - it means hypervisor will co-work with
ACRN UEFI bootloader, restore the context env and de-privilege this env
to VM0 guest.
2. direct-boot: ACRN hypervisor will directly boot different pre-launched
VM(including SOS), it will setup guest env by pre-defined configuration,
and prepare guest kernel image, ramdisk which fetch from multiboot modules.
this patch is trying to:
- rename files related with firmware, change them to guest vboot related
- restruct all guest boot stuff in boot & bsp dirs into a new boot/guest dir
- use de-privilege & direct boot to distinguish two different boot operations
this patch is pure file movement, the rename of functions based on old assumption will
be in the following patch.

For UEFI boot, currently EFI application loads hypervisor to the

this address is not available in the target.
This patch series resolve this issue by allocating memory for hypervisor
at run time, and do relocation fixup if the allocated address is
different from the base address that the hypervisor is built.
The summary of the first patch [1/6] in this series:
In x86_64 ELF, .rela sections hold information of symbols which must be
relocated before being referenced.
This patch adds code to fixup .rela sections with the relocated offset,
also, it provides utilities to assist address fixup

In the hypervisor, physical cpu id is defined as "int" or "uint32_t"
type in the hypervisor. So there are some sign conversion issues
about physical cpu id (pcpu_id) reported by static analysis tool.
Sign conversion violates the rules of MISRA C:2012.
In this patch, define physical cpu id as "uint16_t" type for all
modules in the hypervisor and change related codes. The valid
range of pcpu_id is 0~65534, INVALID_PCPU_ID is defined to the
invalid pcpu_id for error detection, BROADCAST_PCPU_ID is
broadcast pcpu_id used to notify all valid pcpu.
The type of pcpu_id in the struct vcpu and vcpu_id is "int" type,
this will be fixed in another patch.
V1-->V2:
* Change the type of pcpu_id from uint32_t to uint16_t;
* Define INVALID_PCPU_ID for error detection;
* Define BROADCAST_PCPU_ID to notify all valid pcpu.
V2-->V3:
* Update comments for INVALID_PCPU_ID and BROADCAST_PCPU_ID;
* Update addtional pcpu_id;
* Convert hexadecimals to unsigned to meet the type of pcpu_id;
* Clean up for MIN_PCPU_ID and MAX_PCPU_ID, they will be
defined by configuration.
Note: fix bug in the init_lapic(), the pcpu_id shall be less than 8,
this is constraint by implement in the init_lapic().
