Some virtio PCI devices can change the device configuration state, as
reflected in the device-specific configuration region of the device. In
this case:
* If MSI-X capability is disabled:
1. Set the second lower bit of the ISR Status field for the device
2. Send the appropriate PCI interrupt for the device.
* If MSI-X capability is enabled:
1. If config_msix_vector is not NO_VECTOR, request the appropriate
MSI-X interrupt message for the device, config_msix_vector sets
the MSI-X Table entry number.
A single interrupt MAY indicate both that one or more virtqueue has been
used and that the configuration space has changed.

microcode update from UOS is disabled.
microcode version checking is available for both SOS and UOS.
There are two TODOs of this patch:
1. This patch only update the uCode on pCPUs SOS owned. For the
pCPUs not owned by SOS, the uCode is not updated. To handle
this gap, we will have SOS own all pCPUs at boot time. So
all pCPUs could have uCode updated. This will be handled
in the patch to enable SOS own all pCPUs at boot time.
2. gva2gpa now doesn't check possible page table walk failure.
Will add the failure check in gva2gpa in different patch.

As mentioned in https://github.com/projectacrn/acrn-documentation/pull/38
on some operating systems, the ``gnu-efi`` package installs the
linker under a ``gnuefi`` folder in ``${LIBDIR}``. This is the
case in Fedora for example. Check if the gnuefi folder is there
and use it if it is in the path to the linker. This PR fixes the
Makefile rather than documenting how to edit it yourself.

we added uefi stub for hv, and want vm0 continue running under uefi env to
boot other uefi payload (osloader or bzImage).
during this, the uefi timer irq need be handled elegantly.
there are 3 types for uefi timer:
1. 8254 based on IRQ0 of PIC
2. HPET based on IOAPIC
3. HPET based on MSI
currently, we only support type 3 (HPET+MSI). But we are following a
in-correct flow to handle this timer interrupt:
- we set VMX_ENTRY_INT_INFO_FIELD directly if a timer interrupt happened
before vcpu launching, this will make its vlapic mess up, which finally
cause hpet timer stop.
this patch remove this in-correct approach, the new approach patch will
be followed by next patch.

Linux kernel CF9 reboot is doing things like:
- read value from 0xcf9
- mask out the value according to the reboot type (warm vs cold)
- BIT OR the value with reboot code
- write the value to 0xcf9
If there are two reboot event and the first one is cold
reboot and the second one is warm reboot, vsbl query
reboot type after the second one and will get code reboot
instead of warm reboot.
We should clear the data of 0xcf9 if guest request cold reboot.

If you build for a platform (e.g. uefi) and right after that for
another platform ('sbl'), the new build will fail and a version.h
file is left in the tree (bsp/uefi/include/bsp/version.h or
bsp/sbl/include/bsp/version.h depending on the order you built one
after the other). This commit makes git ignore any of those in case
it is there. Note that 'make clean' with the corresponding
PLATFORM variable will clean this file.
