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.

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.

* 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.

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.

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.

"pager" assignment.
* util/biosdisk.c (grub_util_biosdisk_get_grub_dev): Likewise for

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.

* include/grub/util/getroot.h (grub_util_get_grub_dev): Add
prototype.

grub_util_biosdisk_get_grub_dev().
* util/i386/pc/grub-setup.c (main): Likewise.

/, /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.
* util/update-grub.in: Create device.map if it doesn't already exist,
before attempting to run grub-probe.
Check for grub-probe and grub-mkdevicemap with the same code
grub-install is using.
Remove test mode.

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.
* conf/i386-pc.rmk (grub_setup_SOURCES): Add partmap/gpt.c.

and deactivate it afterwards.
* util/i386/pc/grub-install.in: Add gpt module to core.img.
* util/i386/pc/grub-probe.c (main): Activate gpt module for use during
partition identification, and deactivate it afterwards.
* util/grub-emu.c: Move initialization functions
grub_util_biosdisk_init() and grub_init_all() before
grub_util_biosdisk_get_grub_dev(), which relies on them.
./configure --program-transform-name="s/grub/grub2/"
And the installed files (in this case for i386-pc) will be:
/usr/lib/grub2/i386-pc/*
/usr/local/sbin/grub2-emu
/usr/local/sbin/grub2-install
...etc
Also grub2-install place boot files in "/boot/grub2"
This allows easy integration into distributions as it allows grub2 to
sit side by side with a grub legacy install without.

(EXT2_GOOD_OLD_INODE_SIZE): Likewise.
(EXT2_REVISION): Likewise.

instead of 128 to obtain INODES_PER_BLOCK.
Use the macro EXT2_INODE_SIZE instead of directly using
SBLOCK->INODE_SIZE.
* fs/ext2.c (grub_ext2_read_inode): Use the inode size in a
superblock instead of the structure size to compute an
offset. This fixes the problem that GRUB could not read a
filesystem when inode size is different from 128-byte.
* conf/powerpc-ieee1275.rmk (kernel_elf_LDFLAGS): Link at 64KB.
* kern/powerpc/ieee1275/init.c (_end): Add declaration.

* include/grub/err.h (grub_err_t): Add `GRUB_ERR_MENU'.
* kern/env.c (grub_env_unset): Don't free the member `value' when
the type is GRUB_ENV_VAR_DATA, in this case it's a user defined
pointer.

(free_menu): Unset the `menu' environment variable.
(grub_normal_menu_addentry): Make use of the environment variable
`menu', instead of using the global `current_menu'. Allocate
memory for the sourcecode of this entry.
(read_config_file): New argument `nested', changed all callers.
Only in the case of a new context, initialize a new menu. Set the
`menu' environment variable.
(grub_normal_execute): Don't set and unset the environment
variable `menu' here anymore. Only free the menu when leaving the
context.
* util/i386/pc/biosdisk.c (linux_find_partition): Fixed a memory
leak.
* kern/disk.c (grub_disk_read): When there is a read error, always
try to read only the necessary data.

disk/raid.c.
* include/grub/disk.h [GRUB_UTIL] (grub_raid_init): New
prototype.
[GRUB_UTIL] (grub_raid_fini): Likewise.

[GRUB_UTIL] (grub_lvm_fini): Likewise.
* util/i386/pc/grub-probe.c (probe): Check whether DEVICE_NAME is
RAID device and copy DEVICE_NAME to DRIVE_NAME in that case.
(main): Call grub_raid_init(), grub_lvm_init(), grub_lvm_fini()
and grub_raid_fini().
* kern/elf.c (grub_elf_file): Call grub_file_seek. Call
grub_error_push and grub_error_pop in the error-handling path.
(grub_elf32_load_segment): Only call grub_file_read with non-zero
length.
2006-10-18 Jeroen Dekkers <jeroen@dekkers.cx>

Thanks to Michael Guntsche for finding this bug.
* util/i386/pc/grub-probe.c (probe): Print DEVICE_NAME instead of
DRIVE_NAME when grub_util_biosdisk_get_grub_dev fails. Open
DRIVE_NAME instead of DEVICE_NAME. Make sure that DEVICE_NAME and
DRIVE_NAME are always freed.
* util/i386/pc/biosdisk.c (make_device_name): Add one into
DOS_PART, as a DOS partition is counted from one instead of zero
now. Reported by Robert Millan.
