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.

when nvsetenv failed.
* include/grub/i386/pc/kernel.h: Define GRUB_KERNEL_MACHINE_DATA_END to
indicate end of data section in kernel image.

GRUB_KERNEL_MACHINE_DATA_END.

space for it.

* util/i386/pc/grub-mkimage.c: Initialize grub_prefix to /boot/grub
during image generation. Implement --prefix option to override this
patch.

code to make path relative to its root into a separate function.

make_system_path_relative_to_its_root() to convert ${grubdir}, then
pass the result to grub-install --prefix.
* 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.
* conf/powerpc-ieee1275.rmk (kernel_elf_LDFLAGS): Link at 64KB.
* kern/powerpc/ieee1275/init.c (_end): Add declaration.
(_start): Likewise.
(grub_arch_modules_addr): Return address after `_end'.
* util/powerpc/ieee1275/grub-mkimage.c: Include grub/misc.h.
(load_modules): Use new parameter as `p_paddr' and `p_vaddr'.
(add_segments): Calculate `_end' from phdr size and location.
(ALIGN_UP): Moved to ...

* include/grub/powerpc/ieee1275/kernel.h (GRUB_IEEE1275_MOD_ALIGN):
New macro.

* 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.
* normal/main.c (current_menu): Removed.
(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.

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.
