Juergen Gross 4a5733771e libxl: put RSDP for PVH guest near 4GB
Instead of locating the RSDP table below 1MB put it just below 4GB
like the rest of the ACPI tables in case of PVH guests. This will
avoid punching more holes than necessary into the memory map.

Boris Ostrovsky b3afc0a390 libxc/libxl: Allow multiple ACPI modules
Provide ability to load multiple ACPI modules. Thie feature is needed
by PVHv2 guests and will be used in subsequent patches.

We assume that PVHv2 guests do not load their ACPI modules specified
in the configuration file. We can extend support for that in the future
if desired.

Anthony PERARD d57f1a7f3d libxc: Prepare a start info structure for hvmloader
... and load BIOS/UEFI firmware into guest memory.

This adds a new firmware module, system_firmware_module. It is loaded in
the guest memory and final location is provided to hvmloader via the
hvm_start_info struct.

This patch create the hvm_start_info struct for HVM guest that have a
device model, so this is now common code with HVM guest without device
model.

Anthony PERARD 0c42901e12 libxc: Rework extra module initialisation
This patch use xc_dom_alloc_segment() to allocate the memory space for the
ACPI modules and the SMBIOS modules. This is to replace the arbitrary
placement of 1MB (+ extra for MB alignement) after the hvmloader image.

This patch can help if one add extra ACPI table and hvmloader contain
OVMF (OVMF is a 2MB binary), as in that case the extra ACPI table could
easily be loaded past the address 4MB, but hvmloader use a range of
memory from 4MB to 10MB to perform tests and in the process, clears the
memory, before loading the modules.

Roger Pau Monne e260c1c905 libxc: fix leak in xc_dom_load_hvm_kernel error path
Error path in xc_dom_load_hvm_kernel needs to use the 'error' label instead
of directly returning. This is needed so the entries local variable is
freed.

Roger Pau Monne ad787bafcd libxc: introduce a domain loader for HVM guest firmware
Introduce a very simple (and dummy) domain loader to be used to load the
firmware (hvmloader) into HVM guests. Since hmvloader is just a 32bit elf
executable the loader is fairly simple.

Since the order in which loaders are tested cannot be arranged, prevent the
current elfloader from trying to boot a kernel that doesn't contain Xen
ELFNOTES.
