39e3b45422 xen: Init memory regions for PVH
Add all usable memory regions to grub memory management and add the
needed mmap iterate code, which will be used by grub core (e.g.
grub-core/lib/relocator.c or grub-core/mmap/mmap.c).

As we are running in 32-bit mode don't add memory above 4GB.

65ec0f4910 xen: Setup Xen specific data for PVH
Initialize the needed Xen specific data. This is:

- the Xen start of day page containing the console and Xenstore ring
  page PFN and event channel
- the grant table
- the shared info page

Write back the possibly modified memory map to the hypervisor in case
the guest is reading it from there again.

Set the RSDP address for the guest from the start_info page passed
as boot parameter.

d664fffc6d xen: Add basic hooks for PVH in current code
Add the hooks to current code needed for Xen PVH. They will be filled
with code later when the related functionality is being added.

loader/i386/linux.c needs to include machine/kernel.h now as it needs
to get GRUB_KERNEL_USE_RSDP_ADDR from there. This in turn requires to
add an empty kernel.h header for some i386 platforms (efi, coreboot,
ieee1275, xen) and for x86_64 efi.

d43a5ee651 tsc: Use alternative delay sources whenever appropriate.
PIT isn't available on some of new hardware including Hyper-V. So
use pmtimer for calibration. Moreover pmtimer calibration is faster, so
use it on coreboor where booting time is important.

Based on patch by Michael Chang.

316c8d9a18 Make grub_xen_hypercall on i386 cdecl rather than stdcall to avoid
linker trying to "fixup" the code.

9612ebc00e Add new ports: i386-xen and x86_64-xen. This allows running GRUB in
XEN PV environment and load kernels.
