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 ...".
