for powerpc & i386-pc. This patch was more so started by Hollis
Blanchard getting multiboot 2 working for powerpc and I added to it
and cleaned it up.
One of the ideas with this patch is to keep everything under one
command for the user. So instead of having a "multiboot2" & "module2"
command, I created a proxy like mechanism so that you have only one
command for both multiboot 1 & 2 ... "multiboot". This is where
"loader/multiboot_loader.c" comes from. I could have integrated things
more but I figure the current approach will less likely break
anything.
So if your OS is multiboot 2 capable, the user would do the following
to load it up from a grub prompt:
grub> multiboot <location of kernel> <kernel args>
grub> module <some image> <multiboot tag> <image arguments>
grub> module <isome mage> <multiboot tag> <image arguments>
grub .....
The other thing that this patch does is it begins to make the
multiboot 1 code a bit more architecture agnostic so IF someone wanted
to implement it on another architecture they can.
A bit of file moving around and definition renaming is also apart of
this patch. I have also taken the time to make sure that it does not
break multiboot 1 loading on i386-pc. But mulitboot 2 may still need a
little more testing and work for i386-pc. Powerpc multiboot 2 has been
heavily tested and does work.
* geninitheader.sh: Process file specified in first parameter rather
than hardcoding grub_modules_init.lst.
* geninit.sh: Likewise. Also, construct header name dynamicaly rather
than hardcoding grub_modules_init.h.
* conf/common.rmk: Rename grub_modules_init.[ch] files associated with
grub-emu to grub_emu_init.[ch]. Add rules to build analogous
grub_probe_init.[ch] and grub_setup_init.[ch].

grub_setup_init.[ch] files.
* util/grub-emu.c: Replace grub_modules_init.h with grub_emu_init.h.

to initialize modules rather than a list of hardcoded functions.
* util/i386/pc/grub-setup.c: Include grub_setup_init.h. Use
grub_init_all() to initialize modules rather than a list of hardcoded
functions.

flag when running on SmartFirmware.
* term/ieee1275/ofconsole.c (grub_ofconsole_init): Avoid running
"output-device output" command when GRUB_IEEE1275_FLAG_BROKEN_OUTPUT
was set.
* kern/powerpc/ieee1275/openfw.c (grub_ieee1275_encode_devname):
Increase partno when GRUB_IEEE1275_FLAG_0_BASED_PARTITIONS flag is set,
rather than decreasing it.
* util/i386/pc/grub-setup.c (setup): When embedding is required, but
there's not enough space to do it, fail in the same way as when it
can't be done because there are no partitions.
* util/powerpc/ieee1275/grub-install.in: Improve error message shown
when nvsetenv failed.
* conf/i386-pc.rmk (CLEANFILES): Removed for grub-mkrescue,
because this rule is automatically generated.
(grub-mkrescue): Removed for the same reason as above.
* util/i386/efi/grub-install.in: Allow `grub_probe --target=partmap'
invocation to fail, in order to support partition-less media.
* util/i386/pc/grub-install.in: Likewise.
* util/powerpc/ieee1275/grub-install.in: Use grub-probe to determine
which fs or partmap modules are needed (akin to its sister scripts).
Also use grub-probe to get rid of unportable /proc/mounts check.
Print the same informational message that the other scripts do, before
exitting.
* util/update-grub_lib.in (font_path): New function. Determine wether
a font file can be found and, if so, echo the GRUB path to it.
* util/update-grub.in: Handle multiple terminals depending on user
input, platform availability and font file presence. Propagate
variables of our findings to /etc/grub.d/ children.
* util/grub.d/00_header.in: Handle multiple terminals, based on
environment setup by update-grub.
* include/grub/i386/pc/kernel.h: Define GRUB_KERNEL_MACHINE_DATA_END to
indicate end of data section in kernel image.
* include/grub/i386/efi/kernel.h: Define GRUB_KERNEL_MACHINE_PREFIX and
GRUB_KERNEL_MACHINE_DATA_END.
* kern/i386/pc/startup.S: Do not initialize grub_prefix, only reserve
space for it.
* kern/i386/efi/startup.S: Likewise.
* util/i386/pc/grub-mkimage.c: Initialize grub_prefix to /boot/grub
during image generation. Implement --prefix option to override this
patch.
* util/i386/efi/grub-mkimage.c: Likewise.
* util/update-grub_lib.in (convert_system_path_to_grub_path): Split
code to make path relative to its root into a separate function.
* util/i386/pc/grub-install.in: Use newly provided
make_system_path_relative_to_its_root() to convert ${grubdir}, then
pass the result to grub-install --prefix.
* include/grub/util/misc.h: Define DEFAULT_DIRECTORY and
DEFAULT_DEVICE_MAP.
* util/grub-emu.c: Use above definitions from misc.h instead of
defining them.
* util/grub-mkdevicemap.c: Likewise.
* util/i386/pc/grub-setup.c: Likewise.
* util/grub-probe.c: Likewise.
(probe): Abort with grub_util_error() when either
grub_guess_root_device or grub_util_get_grub_dev fails.
* normal/command.c (grub_command_execute): Use NULL rather than 0 for
"pager" assignment.
* util/biosdisk.c (grub_util_biosdisk_get_grub_dev): Likewise for
"pcdata".
* util/grub-probe.c (probe): Likewise for "drive_name".
* util/i386/pc/grub-mkrescue.in: Add "set -e".
Add --pkglibdir=DIR option to override pkglibdir.
Mention --image-type=TYPE in help output.
Fix --grub-mkimage (it was a no-op).
Abort gracefuly when no parameter is given.
* util/update-grub_lib.in (convert_system_path_to_grub_path): Abort if
file doesn't exist, or if it is in a filesystem grub can't read.
* util/update-grub.in: Set fallback for GRUB_FS check to "unknown". Do
not abort if GRUB_DRIVE could not be defined. Rearrange generated
header comment to fit in 80 columns when the variables are resolved.
* util/grub.d/00_header.in: Only set root variable when GRUB_DRIVE
could be identified by update-grub. Remove redundant check for
unifont.pff existance (since convert_system_path_to_grub_path now
handles that).
* conf/powerpc-ieee1275.rmk: Enable grub-mkdevicemap and grub-probe.
* include/grub/partition.h: Declare grub_apple_partition_map_init and
grub_apple_partition_map_fini.
* util/biosdisk.c
(grub_util_biosdisk_open): Replace BLKGETSIZE with BLKGETSIZE64 (needed
to access >2 TiB disks).
Print disk->total_sectors with %llu instead of %lu, since this
variable is always 64-bit (prevents wrong disk size from being displayed
on either >2 TiB disk or big-endian CPU).
(grub_util_biosdisk_get_grub_dev): Convert gpt_partition_map handling
into a generic case that supports all (sane) partition maps.
Stop using grub_cpu_to_le32() on dos_part / bsd_part since it actually
breaks big-endian.

initialize GRUB_DRIVE_BOOT and GRUB_DRIVE_BOOT_GRUB variables.
* util/biosdisk.c (linux_find_partition): Allocate real_dev on the
stack instead of on the heap.
* kern/disk.c (grub_disk_read): Make sure tmp_buf is big enough
before doing a read on it.
* configure.ac: Only use -fno-stack-protector for the target
environment.
* util/getroot.c (grub_guess_root_device): Remove RAID and LVM
code, first search for device in /dev/mapper, then in /dev.
(grub_util_get_grub_dev): New function.
* include/grub/util/getroot.h (grub_util_get_grub_dev): Add
prototype.
* util/grub-probe.c (probe): Remove check for RAID, call
grub_util_get_grub_dev() instead of
grub_util_biosdisk_get_grub_dev().
* util/grub-emu.c (main): Call grub_util_get_grub_dev() instead of
grub_util_biosdisk_get_grub_dev().
* util/i386/pc/grub-setup.c (main): Likewise.
* DISTLIST: Update for the latest changes.
* conf/i386-pc.rmk: Use the new paths for util/getroot.c,
util/grub-mkdevicemap.c, util/grub-probe.c and util/biosdisk.c.

/, /boot and /boot/grub being the same.
* util/grub.d/00_header.in: Likewise.
* util/grub.d/10_hurd.in: Likewise.
* util/grub.d/10_linux.in: Likewise.
* util/grub.d/10_linux.in: Implement Linux image sorting with arbitrary
patterns. Use that to define the `.old' suffix as older than `'.

* util/update-grub.in: Add a reference to ${sysconfdir}/default/grub in
the grub.cfg header message.

determine partition map module.
* util/i386/pc/grub-install.in: Use this feature to decide which
partition module to load, instead of hardcoding pc and gpt.
