- * This is a userspace Linux utility that, when run on the Treo 680, will
- * program u-boot to flash. The docg4 driver *must* be loaded with the
- * reliable_mode and ignore_badblocks parameters enabled:
- *
- * modprobe docg4 ignore_badblocks=1 reliable_mode=1
- *
- * This utility writes the concatenated spl + u-boot image to the start of the
- * mtd device in the format expected by the IPL/SPL. The image file and mtd
- * device node are passed to the utility as arguments. The blocks must have
- * been erased beforehand.
- *
- * When you compile this, note that it links to libmtd from mtd-utils, so ensure
- * that your include and lib paths include this.
