- * Create a flashable NAND image from a binary image
- *
- * History:
- * 1.0 Initial release (tglx)
- * 1.1 Understands hex and dec input parameters (tglx)
- * 1.2 Generates separated OOB data, if needed. (oloh)
- * 1.3 Padds data/oob to a given size. (oloh)
- * 1.4 Removed argp because we want to use uClibc.
- * 1.5 Minor cleanup
- * 1.6 Written variable not initialized (-j did not work) (haver)
- * 1.7 Made NAND ECC layout configurable (haver)
