Add support for oobsize 64 and writesize 4096 in nanddump & nandwrite.
Artem: some more info from further e-mail exchange:
> Are there flashes with the 4096 page / 64 spare combination? Could you
> refer to one? May be any URL? I thought 4096 comes with 128.
Much to my regret I can't provide a URL because is not public. IGEP v2
board has a Onenand with two dice of 2048/64 spare combination but mtd
views 4096/64. The minimal write page is 4K (2K from first dice and 2K
from second dice).

The tool mkyaffs2image doesn't know the oob layout of a NAND flash, so it
puts the yaffs2 tags at the offset 0 of oob area, as a result, the image
generated by mkyaffs2image is different with the image dumped by nanddump.
Now adding a parameter "-r" for nandwrite to differentiate these images.
Write a image generated by mkyaffs2image:
$> nandwrite -a -o /dev/mtd3 yaffs2.bin
Write a image dumped by nanddump:
$> nandwrite -a -r /dev/mtd3 image.bin

This reverts commit 13b77ef356e876f42f489f6a08840e12847135c5.
We do not support block devices. This patch was pushed by accident.

struct ubi_attach_request now has additional field 'dev' that can contain path
to the MTD device node in the filesystem. Also there are two new functions that
are able to handle path to the MTD device node:
ubi_attach() - attach MTD device by number or by path
ubi_detach() - detach MTD device by path
ubi_attach() works like ubi_attach_mtd() when it is passed empty req->dev,
otherwise it looks up correct MTD device number based on the given device node
path.

Not all systems have largefile support (E.G. uClibc depending on config),

This commit fixes a stupid an nasty bug. When we flash an UBI image,
we do not change its sequence numbers. But when we format the rest
of the PEBs (beyond the flashed image), we use a random (or specified
via cmdline) sequence number. As a result, we have a broken flash
format and UBI refuses it, because half of it has one sequence number,
another half has a different one.
What we have to do instead, we have to substitute image's sequence
number with ours.

This patch enhances the flash_unlock utility to be able to do
unlocking for specified blocks range.
This patch also fixes calculation of 'length' as in previous patch.
Say there are 240 blocks present in the device. Then:
offset starts from: 0x0
and full size of device: 0x1E00000
doing: 240 * 0x20000 gives -> 0x1E00000
But last block address should be 0x1DE0000 (which spans for 0x20000
bytes, adding up to size of 0x1E00000)

This patch fixes the 'length' calculation.

+ mtdLockInfo.length = (num_sectors - 1) * mtdInfo.erasesize;

- mtdLockInfo.length = num_sectors * mtdInfo.erasesize;

args.image_seq is of type uint32_t and was initialized to -1 which
becomes 0xFFFFFFFF in this case. Later the value -1 was used as a flag
that args.image_seq should be replaced with a randomized value.
With the option --image-seq (-Q) a user could provide any sequence
number at will.
But when the user provided sequence number was 0xFFFFFFFF this was
understood effectivly as -1 and got overridden by a randomized
sequence number.
So this patch change the programm flow to respect the principle of
least surprise and never use a randomized sequence number when the
user provide one at own will.

Nandwrite tries to use lseek() when failing to write on a page. lseek()
will fail when used on the standard input so nandwrite fails. This code
replaces lseek with a buffer.
When the data is read, it is put in a buffer (filebuf). This buffer is
reset at each block boundary. So a "seek" just means reading from the
beginning of the buffer. writebuf and oobreadbuf are now just pointers
to locations in filebuf.

With the device table one can add /dev entries to the root file system
image. The device table file contains among others the fields minor,
start, increment and count. If there is an entry with minor=0 start=0
increment=32 and count=4 the mkfs.ubifs makes 128 device entries, with
minor numbers from 0 to 127. The correct version makes 4 entries with
minor number 0,32,64,96.
/dev/mtd c 640 0 0 90 0 0 2 7
This gives 14 devices /dev/mtdXX instead of 7 devices.
Due to this error mtd_debug info /dev/mtd3 delivers the information of
/dev/mtd1 instead of.
