OneNAND Initial Program Loader (IPL) support
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. Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
