* disk/ieee1275/ofdisk.c (grub_ofdisk_iterate): Cast `size' to long.

	* include/grub/ieee1275/ieee1275.h (grub_ieee1275_next_property):
	Remove `flags' argument.  All callers changed.
	* kern/ieee1275/ieee1275.c (IEEE1275_PHANDLE_ROOT): Removed.
	(IEEE1275_IHANDLE_INVALID): New variable.
	(IEEE1275_CELL_INVALID): New variable.

	grub_ieee1275_peer, grub_ieee1275_child, grub_ieee1275_open,
	grub_ieee1275_claim, grub_ieee1275_set_property): Error-check return
	codes from Open Firmware.  All callers updated.
	(grub_ieee1275_next_property): Directly return Open Firmware return
	code.
	* kern/powerpc/ieee1275/cmain.c (grub_ieee1275_find_options):
	Standardize error checking from `grub_ieee1275_get_property'.
	* kern/powerpc/ieee1275/openfw.c (grub_devalias_iterate): Rename
	`devalias' to `aliases'.  Correct comments.  Consolidate error paths.
