        * include/grub/dl.h: Include grub/elf.h.
        (struct grub_dl): Add symtab field.
        * kern/dl.c [GRUB_MACHINE_QEMU]: Define
        GRUB_MODULES_MACHINE_READONLY.
        (grub_dl_resolve_symbols): Populate mod->symtab, making a copy
        of the header for read-only modules.
        (grub_dl_unload): Free mod->symtab for read-only modules.
        * kern/i386/dl.c: Use mod->symtab.
        * kern/powerpc/dl.c: Likewise.
        * kern/sparc64/dl.c: Likewise.
        * kern/x86_64/dl.c: Likewise.

        * conf/i386-qemu.rmk: New file.
        * kern/i386/qemu/startup.S: Likewise.
        * kern/i386/qemu/mmap.c: Likewise.
        * boot/i386/qemu/boot.S: Likewise.
        * include/grub/i386/qemu/time.h: Likewise.

        * include/grub/i386/qemu/memory.h: Likewise.

        * conf/i386-coreboot.rmk (GRUB_BOOT_MACHINE_LINK_ADDR)
        (GRUB_KERNEL_MACHINE_LINK_ADDR): New variables.
        [qemu] (pkglib_IMAGES): Add `boot.img'.
        [qemu] (boot_img_SOURCES, boot_img_ASFLAGS, boot_img_LDFLAGS)
        [qemu] (boot_img_FORMAT): New variables.
        [qemu] (bin_UTILITIES): Add `grub-mkimage'.
        [qemu] (grub_mkimage_SOURCES, grub_mkimage_CFLAGS): New variables.

        * configure.ac: Recognise `i386-qemu'.

        * util/i386/pc/grub-mkimage.c (compress_kernel): Add dummy variant
        (for no compression).
        [GRUB_MACHINE_QEMU] (generate_image): Misc adjustments to produce
        a valid i386 ROM image.  Make `GRUB_KERNEL_MACHINE_COMPRESSED_SIZE',
        `GRUB_KERNEL_MACHINE_INSTALL_DOS_PART' and
        `GRUB_KERNEL_MACHINE_INSTALL_BSD_PART' optional features (with
        ifdefs).
