This patch adds the NAND SPL framework needed to boot i.MX31 boards
from NAND.
It has been tested on a i.MX31 PDK board with large page NAND. Small
page NANDs should work as well, but this has not been tested.
Note: The i.MX31 NFC uses a non-standard layout for large page NANDs,
whether this is compatible with a particular setup depends on how
the NAND device is programmed by the flash programmer (e.g. JTAG
debugger).
The patch is based on the work by Maxim Artamonov.

Currently CONFIG_ONENAND_IPL is used in a number of #ifdef's
in start.S. In preparation for adding support for NAND SPL
the macro CONFIG_PRELOADER is introducted and replaces the
CONFIG_ONENAND_IPL in start.S.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Reverting became necessary after it turned out that the patches in
the u-boot-arm repo were modified, and in some cases corrupted.

This patch enables the OneNAND boot within U-Boot.
Before this work, we used another OneNAND IPL called X-Loader based
on open source. With this work, we can build the oneboot.bin image
without other program.
The build sequence is simple.
First, it compiles the u-boot.bin
Second, it compiles OneNAND IPL
Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin
The mechanism is similar with NAND boot except it boots from itself.
Another thing is that you can only use the OneNAND IPL only to work
other bootloader such as RedBoot and so on.
