	change the buffer size to 4096 for cdrom device.

	* conf/i386-ieee1275.rmk (pkglib_MODULES): Add _linux.mod, linux.mod
	and nand.mod.
	(_linux_mod_SOURCES): New variable.
	(_linux_mod_CFLAGS): Likewise.

	(nand_mod_SOURCES): Likewise.
	(nand_mod_CFLAGS): Likewise.
	(nand_mod_LDFLAGS): Likewise.

	* disk/ieee1275/ofdisk.c (grub_ofdisk_open): Return
	GRUB_ERR_UNKNOWN_DEVICE instead of GRUB_ERR_BAD_DEVICE if no device
	type property. (nand device in olpc don't have this property)

	* include/grub/disk.h (grub_disk_dev_id): New macro
	GRUB_DISK_DEVICE_NAND_ID.

	* include/grub/i386/ieee1275/loader.h (grub_rescue_cmd_linux): New
	function prototype.
	(grub_rescue_cmd_initrd): Likewise.

	* include/grub/i386/linux.h (GRUB_LINUX_OFW_SIGNATURE): New macro.
	(linux_kernel_params): Add new member ofw_signature, ofw_num_items,
	ofw_cif_handler and ofw_idt, adjust padding number.

	* include/grub/i386/pc/memory.h (grub_upper_mem): Export it if
	GRUB_MACHINE_IEEE1275 is defined.

	* include/grub/ieee1275/ieee1275.h (grub_available_iterate):
	Use NESTED_FUNC_ATTR attribute on the hook parameter.

	* kern/powerpc/ieee1275/init.c (grub_claim_heap): Use NESTED_FUNC_ATTR
	on nested function heap_init.
	(grub_upper_mem): New variable for i386-ieee1275.
	(grub_get_extended_memory): New function for i386-ieee1275.
	(grub_machine_init): Call grub_get_extended_memory for i386-ieee1275.

	* kern/powerpc/ieee1275/openfw.c (grub_available_iterate): Use
	NESTED_FUNC_ATTR on the hook parameter. Don't quit if no device type
	property.

	* loader/i386/ieee1275/linux.c: New file.

	* loader/i386/ieee1275/linux_normal.c: New file.
