Hi, If you want you can change the partition scheme by editing the partition table in arch/arm/mach-davinci/board-dm355-evm.c
Be warned - do not change the 'bootloader', 'params' or 'kernel' partitions. You probably could make the 'kernel' partition a bit smaller but at 4M you can fit a kernel + initial ramdisk or perhaps 2 kernels depending on what you want to do. Also note that the larger partitions take longer to mount and 'first access' times also increase (especially JFFS2) so it isn't always good to have a single large partition for the root filesystem.
