19ffaa50dc HV: init and sanitize acrn multiboot info
Initialize and sanitize a acrn specific multiboot info struct with current
supported multiboot1 in very early boot stage, which would bring below
benifits:

- don't need to do hpa2hva convention every time when refering boot_regs;

- panic early if failed to sanitize multiboot info, so that don't need to
  check multiboot info pointer/flags and panic in later boot process;

- keep most code unchanged when introduce multiboot2 support in future;

520a0222d3 HV: re-arch boot component header
The patch re-arch boot component header files by:

- moving multiboot.h from include/arch/x86/ to boot/include/ and keep
  this header for multiboot1 protocol data struct only;

- moving multiboot related MACROs in cpu_primary.S to multiboot.h;

- creating an independent boot.h to store acrn specific boot information
  for other files' reference;

7e66c0d4fa hv: sched: use get_running_vcpu to replace per_cpu vcpu with cpu sharing
With cpu sharing enabled, per_cpu vcpu cannot work properly as we might
has multiple vcpus running on one pcpu.
Add a schedule API sched_get_current to get current thread_object on
specific pcpu, also add a vcpu API get_running_vcpu to get corresponding
vcpu of the thread_object.

7d43a93fb7 HV: validate multiboot cmdline before merge cmdline
In grub 2.02, the flag of MULTIBOOT_INFO_HAS_CMDLINE is set even there is
no cmdline was configured. So we need to validate the content of cmdline
in multiboot info. If there is no cmdline exist, we should not do merge
cmdline for SOS VM.

1906def29e HV: enable load zephyr kernel
Zephyr kernel is stripped ram image, its entry and load address
are explicitly defined in vm configurations, hypervisor will load
Zephyr directly based on these configurations.

Currently we only support boot Zephyr from protected mode.

ea7ca8595c HV: use tag to specify multiboot module
Previously multiboot mods[0] is designed for kernel module for all
pre-launched VMs including SOS VM, and mods[0].mm_string is used
to store kernel cmdline. This design could not satisfy the requirement
of hybrid mode scenarios that each VM might use their own kernel image
also ramdisk image. To resolve this problem, we will use a tag in
mods mm_string field to specify the module type. If the tag could
be matched with os_config of VM configurations, the corresponding
module would be loaded;

d0fa83b2cb HV: move sos bootargs to vm configurations
Previously the bootargs of SOS_VM is stored in a text file and stitched
into multiboot mods[0].string whereas the bootargs of PRE_LAUNCHED_VM is
stored in vm_configurations.c. Given the mods[].string will be used to
store Kernel image signature under hybrid mode, move the bootargs of SOS_VM
to vm configurations also to make it consistent with PRE_LAUNCHED_VM;

238d8bbaa2 reshuffle init_vm_boot_info
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.
