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.

grub_machine_mmap_iterate() interface (fixes a recently-introduced
build problem on i386-ieee1275):
* kern/ieee1275/openfw.c (grub_available_iterate): Moved from here ...
* kern/ieee1275/mmap.c (grub_machine_mmap_iterate): ... here. Add third
parameter `type'. Update all users of this function.
* conf/i386-ieee1275.rmk (kernel_elf_SOURCES): Add
`kern/ieee1275/mmap.c'.
* kern/ieee1275/init.c
* include/grub/ieee1275/ieee1275.h (grub_available_iterate): Replace
with ...
(grub_machine_mmap_iterate): ... this.
* include/grub/i386/pc/memory.h (grub_machine_mmap_iterate): Change
return type to `grub_err_t'. Update all implementations of this
function prototype.
* include/grub/i386/coreboot/memory.h (grub_machine_mmap_iterate):
Likewise.
* include/grub/i386/coreboot/memory.h (GRUB_MEMORY_MACHINE_LOWER_SIZE):
Redefine to match with GRUB_MEMORY_MACHINE_UPPER_START (0x100000). We
don't want to mess with lower memory, because it is used in the Linux
loader.
* loader/i386/linux.c (allocate_pages): Allocate `real_mode_mem' in
an appropiate place in lower memory, between 0x10000 and 0x90000,
like loader/i386/efi/linux.c does. Linux often panics if real_mode_mem
is in our heap (probably as a result of it being corrupted during
decompression).
Use newly-added Multiboot support in coreboot.
* conf/i386-coreboot.rmk (kernel_elf_SOURCES): Replace
`kern/i386/coreboot/mmap.c' with `kern/i386/multiboot_mmap.c'.
* kern/i386/coreboot/startup.S: Enable Multiboot header, fix its
alignment, set `MULTIBOOT_MEMORY_INFO' flag.
(codestart): Store the MBI in `startup_multiboot_info' when we're
being loaded using Multiboot.
* kern/i386/coreboot/init.c (grub_machine_init): Move
grub_at_keyboard_init() call to beginning of function (useful for
debugging). Call grub_machine_mmap_init() before attempting to use
grub_machine_mmap_iterate().
(grub_lower_mem, grub_upper_mem): Move from here ...
* kern/i386/multiboot_mmap.c (grub_lower_mem, grub_upper_mem): ... to
here (new file).
* include/grub/i386/coreboot/memory.h (grub_machine_mmap_init): New
function prototype.
Modularize at_keyboard.mod:
