Introduction
============
-Having looked at the linux mtd/nand driver and more specific at nand_ecc.c
+Having looked at the linux mtd/nand Hamming software ECC engine driver
I felt there was room for optimisation. I bashed the code for a few hours
performing tricks like table lookup removing superfluous code etc.
After that the speed was increased by 35-40%.
