The options used in the creation of the filesystem image mean:
-r <rootfs>: to create an UBIFS image containing the rootfs directory;
-m 4096: to set the minimum input/output unit size of the flash (NAND
page in this case);
-e 520192: to indicate the logical eraseblock size of the UBI volume;
-c 1980: to set the maximum file-system size in logical eraseblocks;
the resulting filesystem may be put on volumes up to about 982MiB
