bd78bc6b2a NAND: Properly create JFFS2 cleanmarkers.
As reported by Ilko Iliev <iliev@ronetix.at>, the "nand erase clean"
command is currently broken, and among other things causes all blocks
to be marked bad.

This implements it properly using MTD_OOB_AUTO, along with some
indentation fixes.

cfa460adfd Update MTD to that of Linux 2.6.22.1
A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.

This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.

MAKEALL ppc/arm has some issues:
 * DOC/OneNand/nand_spl is not building (I have not tried porting
   these parts, and since I do not have any HW and I am not familiar
   with this code/HW I think its best left to someone else.)

Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:
 cpu/ppc4xx/ndfc.c
 cpu/arm926ejs/davinci/nand.c
 board/delta/nand.c
 board/zylonite/nand.c

e870690bdc MTD/NAND: Fix printf format warning in nand code
This patch fixes NAND related printf format warning. Those warnings are
now visible since patch dc4b0b38d4
[Fix printf errors.] by Andrew Klossner has been applied. Thanks, this is
really helpful.

9723bbb46a nand: Correct NAND erase percentage output
For NAND erase sizes smaller than one NAND erase block, erase
percentage output becomes grater than 100% e.g.

-- cut --
  > nand info
Device 0: NAND 64MiB 1,8V 8-bit, sector size 16 KiB
  > nand erase 0x100000 0x2000
NAND erase: device 0 offset 0x100000, size 0x2000
Erasing at 0x100000 -- 200% complete.
OK
  >
-- cut --

Correct this and give user a warning that more is erased than specified:

-- cut --
  > nand erase 0x100000 0x2000
NAND erase: device 0 offset 0x100000, size 0x2000
Warning: Erase size 0x00002000 smaller than one erase block 0x00004000
           Erasing 0x00004000 instead
Erasing at 0x100000 -- 100% complete.
OK
  >
-- cut --
