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].
* conf/powerpc-ieee1275.rmk (grub_emu_DEPENDENCIES): Replace
grub_modules_init.h with grub_emu_init.h.

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

and grub_apple_partition_map_fini() after that.
