This patch introduces configuration options allowing to built either a
rombios only or a seabios only hvmloader.
Building option ROMs like vgabios or etherboot is only enabled for a
rombios hvmloader, since SeaBIOS takes care or extracting option ROMs
itself from the PCI devices (these option ROMs are provided by the
device model and do not need to be built in hvmloader).
The Makefile in tools/firmware/ now only checks for bcc if rombios is
enabled.
These two configuration options are left on by default to remain
compatible.

The Intel GPU uses a two pages NVS region called OpRegion.
In order to get full support for the driver in the guest
we need to map this region.
This patch reserves 2 pages on the top of the memory in the
reserved area and mark this region as NVS in the e820. Then
we write the address to the config space (offset 0xfc) so the
device model can map the OpRegion at this address in the guest.

Change the way we relocate the memory page if they overlap with pci

into xen.
This code usually get triggered when a device is pass through to a
guest and the PCI hole has to be extended to have enough room to map
the device BARs. The PCI hole will starts lower and it might overlap
with some RAM that has been alocated for the guest. That usually
happen if the guest has more than 4G of RAM. We have to relocate
those pages in high mem otherwise they won't be accessible.

The ACPI PIIX4 device in QEMU upstream as not the same behavior to
handle PCI hotplug. This patch introduce the necessary change to the
DSDT ACPI table to behave as expceted by the new QEMU.
To switch to this new DSDT table version, there is a new option
--dm-version to mk_dsdt.
Change are inspired by SeaBIOS DSDT source code.
There is few things missing with the new QEMU:
- QEMU provide the plugged/unplugged status only per slot (and not
per func like qemu-xen-traditionnal.
- I did not include the _STA ACPI method that give the status of a
device (present, functionning properly) because qemu-xen does not
handle it.
- I did not include the _RMV method that say if the device can be
removed,
because the IO port of QEMU that give this status always return
true. In
SeaBIOS table, they have a specific _RMV method for VGA, ISA that
return
false. But I'm not sure that we can do the same in Xen.
So, the only way to remove a device is from outside of the guest (like
with xl pci-detatch), and can not be initiated from inside.

SeaBIOS will reserve memory in the e820 as necessary, including BIOS
data structures such as the EBDA, any tables it creates or copies into
pleace etc. Therefore arrange that the memory map provided by
hvmloader to SeaBIOS reserves only things which HVMloader has created.
Since ROMBIOS is more tightly coupled with hvmloader we retain the
ability to reserve BIOS regions in the hvmloader produced e820 and use
that from the ROMBIOS backend.
The code for this could probably have been simpler but the existing
code avoids overlapping e820 areas and so the new code does the same
(many guest OSes sanitize the e820 map to handle this, but I wouldn't
trust that all do, so I didn't take the risk)
For ROMBIOS the resulting e820 map as seen by the guest is the same
except the reserved regions at 0x9e000-0x9fc00,0x9fc00-0xa0000 are
merged into a single region 0x9e000-0xa0000 (Linux guests sanitize the
e820 to look like this anyway).
For SeaBIOS the result is that the lowmem reserved region is from
0x9f000-0xa0000 rather than 0x9e000-0xa0000 which correctly reflects
SeaBIOS's actual usage.
