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.

[!GRUB_UTIL] (my_mod): New variable.
* util/grub-emu.c (main): Call grub_xfs_init and grub_xfs_fini.
* kern/i386/pc/startup.S (gate_a20_try_system_control_port_a):
When turning off Gate A20, skip the check and return immediately,
because this is not fatal usually.
* conf/i386-pc.rmk (pxeboot_img_LDFLAGS): The text address should
be 0x7C00 instead of 0x8000.
* boot/i386/pc/pxeboot.S: Rewritten.
* kern/i386/pc/startup.S (gate_a20_try_bios): No need to specify
EXT_C.
(gate_a20_check_state): Read a byte from 0x108000. Invert the
result.
* kern/i386/pc/startup.S (grub_gate_a20): Rewritten for
robustness. This routine now supports a BIOS call and System
Control Port A to modify the gate A20.
* include/grub/i386/pc/kernel.h (GRUB_KERNEL_MACHINE_RAW_SIZE):
Increased to 0x440.
All symbols prefixed with PUPA_ and pupa_ are renamed to GRUB_
and grub_, respectively. Because the conversion is trivial and
mechanical, I omit the details here. Please refer to the CVS
if you need more information.
* disk/i386/pc/biosdisk.c (pupa_biosdisk_open): Correctly check
for available extensions.
* include/pupa/i386/pc/time.h: New file.
* kern/disk.c: Include <pupa/machine/time.h>.
(PUPA_CACHE_TIMEOUT): New macro.
(pupa_last_time): New variable.
(pupa_disk_open): Flush the cache when there was a timeout.
(pupa_disk_close): Reset the timer.
* kern/i386/pc/startup.S (pupa_get_rtc): Renamed from
pupa_currticks.
* util/misc.c: Include <sys/times.h>
(pupa_get_rtc): New function.
I forgot to check in these changes for a long time. This adds
incomplete support for VGA console, and this is still very
buggy. Also, a lot of consideration is required for I18N,
UNICODE, and VGA font issues. Therefore, assume that this is
such that "better than nothing".
* font/manager.c: New file.
* include/pupa/font.h: Likewise.
* include/pupa/i386/pc/vga.h: Likewise.
* term/i386/pc/vga.c: Likewise.
* util/unifont2pff.rb: Likewise.
* conf/i386-pc.rmk (kernel_img_HEADERS): Added machine/vga.h.
(pkgdata_MODULES): Added vga.mod and font.mod.
(vga_mod_SOURCES): New variables.
(vga_mod_CFLAGS): Likewise.
(font_mod_SOURCES): Likewise.
(font_mod_CFLAGS): Likewise.
* include/pupa/err.h (PUPA_ERR_BAD_FONT): New constant.
* include/pupa/term.h: Include pupa/err.h.
(struct pupa_term): Added init and fini.
Changed the argument of putchar to pupa_uint32_t.
* include/pupa/i386/pc/console.h: Include pupa/symbol.h.
(pupa_console_real_putchar): New prototype.
(pupa_console_putchar): Removed.
(pupa_console_checkkey): Exported.
(pupa_console_getkey): Likewise.
* kern/misc.c (pupa_vsprintf): Add support for UNICODE
characters.
* kern/term.c (pupa_term_set_current): Rewritten.
(pupa_putchar): Likewise.
(pupa_putcode): New function.
* kern/i386/pc/startup.S (pupa_console_putchar): Renamed to ...
(pupa_console_real_putchar): ... this.
(pupa_vga_set_mode): New function.
(pupa_vga_get_font): Likewise.
* normal/command.c: Include pupa/term.h.
(terminal_command): New function.
(pupa_command_init): Register the command "terminal".
* normal/menu.c (DISP_LEFT): Changed to a UNICODE value.
(DISP_UP): Likewise.
(DISP_RIGHT): Likewise.
(DISP_DOWN): Likewise.
(DISP_HLINE): Likewise.
(DISP_VLINE): Likewise.
(DISP_UL): Likewise.
(DISP_UR): Likewise.
(DISP_LL): Likewise.
(DISP_LR): Likewise.
* term/i386/pc/console.c (pupa_console_putchar): New function.
