This patch makes the Service OS bootloader configurable by passing
a command-line argument to 'acrn.efi' when setting up the EFI
bootloader using, e.g., 'efibootmgr'. If no argument is passed, the
default bootloader used is: "\EFI\org.clearlinux\bootloaderx64.efi".
This is the default bootloader/setting used by Clearlinux and is set
in the bsp/uefi/include/bsp/bsp_cfg.h file (via the
CONFIG_UEFI_OS_LOADER_NAME define)
The general format of the argument is: "bootloader=<\path\to\bootloader>".
As a concrete example, imagine the following set-up:
* You have installed the Service OS (bare-metal for now)
* Bootloader is "\EFI\org.clearlinux\bootloaderx64.efi"
* Boot device is '/dev/sda'
* EFI System Partition (ESP) is '1'
* You put the ACRN hypervisor under "\EFI\acrn\"
To change the default boot entry to boot the ACRN hypervisor, enter:
# efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/sda -p 1 \
-L "ACRN Hypervisor" -u "bootloader=\EFI\org.clearlinux\bootloaderx64.efi"
And reboot your machine.

currently, pass-thru devices are managed by per-vm's remapping entries
which is virtual based:
- MSI entry is identified by virt_bdf+msix_index
- INTx entry is identified by virt_pin+vpin_src
it works but it's not a good design for physical resource management, for
example a physical IOAPIC pin could belong to different vm's INTx entries,
the Device Model then must make sure there is no resource conflict from
application's level.
This patch change the design from virtual to physical based:
- MSI entry is identified by phys_bdf+msix_index
- INTx entry is identified by phys_pin
The physical resource is directly managed in hypervisor, a miss adding
entry will be found by hypervisor and return error message with failure.

The launch script can output log messages, that should be text.
But it is not always true. E.g. "launch_UOS.sh -U 2" echo message
contain '\0', The 'grep' command will show "Binary file (xxxxxx)
