This patch adds framework for dual format images. Format detection is added
and the bootm controll flow is updated to include cases for new FIT format
uImages.

When the legacy (image_header based) format is detected appropriate
legacy specific handling is invoked. For the new (FIT based) format uImages
dual boot framework has a minial support, that will only print out a
corresponding debug messages. Implementation of the FIT specific handling will
be added in following patches.

Fix usage of do_div() in nand erase|read|write process output.

The last patch to nand_util.c introduced do_div() instead of libgcc's
implementation. But do_div() returns the quotient in its first
macro parameter and not as result.

This config option sets the default for the progress information
output behavior that can also be configured through the 'quiet'
environment variable.

The legacy NAND code does not print the current progress info
on the console. So this option is for backward compatibility for
units that are in the field and where setting the quiet variable
is not an option. With CFG_NAND_QUIET set to '1' the console
progress info is turned off. This can still be overwritten
through the environment variable.

The old implementation of command nboot does not support reading the image from
NAND flash with skipping of bad blocks. The patch implements a new version of
the nboot command: by calling nboot.jffs2 from the u-boot command line the
command will load the image from NAND flash with respect to bad blocks (by using
nand_read_opts()). This is similar to e.g. the NAND read command: "nand
read.jffs2 ...".

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

BOARDLIBS = drivers/nand_legacy/libnand_legacy.a added. Build breakage for
NETTA.ERR and NETTA_ISDN - will go away when the new NAND support is
implemented for these boards.
