[patch] PPC build fixes


From: Hollis Blanchard
Subject: [patch] PPC build fixes
Date: Sat, 19 Feb 2005 17:34:40 -0600
User-agent: Mutt/1.5.6+20040907i

This patch fixes PowerPC build breakage from the recent grub-emu changes. Of
note:

- grub_reboot and grub_halt in util/i386/pc/misc.c are not
  architecture-specific, so have been moved to util/grub-emu.c.

- commands/ieee1275/halt.c and reboot.c are no longer
  architecture-specific either. This is because we now want those
  commands to be loaded in grub-emu, and of course grub-emu does not
  emulate Open Firmware. Accordingly, these files are moved up to the
  commands directory. Since i386 needs a special argument ("no-apm"), it
  still uses its version in commands/i386/pc.

- since grub_machine_fini isn't called yet, I haven't yet figured out
  how to release the memory indicated in the comments.

OK?
