As mentioned before, this is off topic here.
A few comments anyway:

For an uncompressed image the size if very small. Are you sure this is OK?

This kernel version is extremely old. You will not find much support
for it any more.

You boot with a ramdisk, but put the root file system on a MTD
device? Strange.
The "/dev/mtdblock/2" suggests that you are attemptiong to use devfs.
IMHO not a good idea.
Also, the "init=/linu0" is strange.

Your kernel seems to have a bug when printing the serial port names.

Are you sure there is actually a root file system in your MTD
partition?
