79d29fd7b8 Harmonize ieee1275's grub_available_iterate() with the generic 
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.
