Can you still boot the system in nand? If yes, check dmesg output for 2 things:
The kernel commandline should look similar to this:
[ 0.000000] Kernel command line: rootfstype=jffs2
root=/dev/mtdblock6 console=ttySAC2,115200 console=tty0 loglevel=4
regular_boot mtdparts=physmap-flash:-(nor);neo1973-nand:0x00040000(u-boot),0x00040000(u-boot_env),0x00800000(kernel),0x000a0000(splash),0x00040000(factory),0x0f6a0000(rootfs)
And somewhat later:
[ 1.300000] 6 cmdlinepart partitions found on MTD device neo1973-nand
[ 1.305000] Creating 6 MTD partitions on "neo1973-nand":

Maybe you u-boot environment is damaged?
