Changes

*<code>mtd0</code>, <code>mtd1</code>, and <code>mtd2</code> are significantly larger than the files they store used in this example. This allows having a spare room to store larger images. For the sake of simplicity, however, U-Boot was configured to read the whole partitions. Obviously, these affect the overall boot time negatively. To optimize it, (see how the <code>loadunand</code>, <code>loadfdtnand</code>, and <code>loadfpga2</code> variables are defined). Obviously, this affect the overall boot time negatively. To optimize it, these variables have to be changed in order to read read just the required amount of data according to the size of the actual stored files.*As stated previously, the root filesystem is <code>initramfs</code> and thus not persistent. Consequently, every it is mountedtime the system boots, the directory <code>/mnt/data3</code> must be createdbefour mounting the ''UBIFS'' file system stored in the NAND flash.
