Since hvmloader has a xentore client, use a platform key in xenstore
to indicate whether ACPI is enabled or not rather than the shared
hvm_info_table structure.

When booting a Windows guest, the OS report an issue with the ACPI (in
a BSOD). The exact issue is "SCI_EN never becomes set in PM1 Control
Register." (quoted from WinDbg help).
So this patch enables the flags SCI_EN if it is not yet enabled.

Currently we have ->bios_high_setup, which is called relatively early
and returns a cookie which is passed to ->bios_info_setup which runs
towards the end and creates the BIOS info, incorporating the cookie
which (in the case of ROMBIOS) happens to be the BIOS's high load
address . This is rather ROMBIOS specific.
Refactor to have ->bios_info_setup which is called early and prepares
the bios_info, ->bios_relocate which does any necessary relocation
(updating the BIOS info as necessary) and ->bios_info_finish which
finalises the info (e.g. by calculating the checksum).

Returns memory which is passed to the subsequent BIOS but can be
reused once the contents is consumed. An example of this would be a
BIOS table which the BIOS consumes by copying rather than simply
referencing.
Users which need a temporary scratch buffer for internal use
scratch_start which follows these allocations.

SeaBIOS has functionality to load ROMs from the PCI device directly,
it makes sense to use this when it is available.
Signed-off-by: Ian Campbell <ian.campbell@citrix.com>
The SeaBIOS integration here is only semi-complete and is targetted at
developers and very early adopters who can be expected to cope with
some rough edges. In particular the user must clone, patch as
necessary and compile SeaBIOS themselves since this patchset does not
cover any of that (in the same way we currently do not integrate
upstream qemu clone+build). Include a big comment to that effect next
to the Config.mk option.
Many of the bios_config callback functions are not yet used by
SeaBIOS.

Pass the table address as a paramter to the build function and cause
it to return the number of entries. Pass both base and offset as
parameters to the dump function.
This adds a duplicated e820.h header to ROMBIOS. Since the e820 data
structure is well defined by existing BIOS implementations I think
this is OK and simplifies the cross talk between hvmloader and
ROMBIOS.

hvmloader is responsible for - amoungst other things - initialising
the PCI device BARs prior to loading the guest BIOS. The previous
code only probed for devfn up to 128. The lower 3 bits are function
IDs so this meant that only devices in slots 0-15 were actually being
initialized.

As part of the QEMU/Xen merge, this patch comes to change the value of
sleep states and add some information in the PCI registers to match the
implementation of the BIOS of QEMU.
It also does a hypercall (HVM_PARAM_ACPI_IOPORTS_LOCATION) that tell the
Xen to use the new Port I/O instead of the old one.
[ Also, in this patch, update QEMU_TAG to the qemu-xen revision
with the corresponding qemu change. -iwj ]

When graphics card is assigned to a guest as a secondary VGA,
without gfx_passthru and emulated VGA is the primary VGA,
hvmloader misreads gfx_passthru is specified if VGA device is
found after the emulated VGA.
This patch fix this issue. If emulated VGA is found, hvmloader
preserves it and loads vgabios of the emulated VGA.

In order to support HVM vcpu add/remove, we need set dsdt
infrastructure.
-- By using mk_dsdt.c, it auto-produce related asl code when
compiling.
-- It define processor related objects and control methods (_MAT,
_EJ0, _STA, etc).
-- It also define GPE _L02 and Notify control method for SCI
interrupt, which will trigger HVM acpi driver to add/remove cpu.
