Bootldr copies the data 512+16 bytes at a time into non-broken NAND. The kernel is then booted with prior knowledge as to where to find the YAFFS data and all is ok. How this works with DOC I am unclear as I had noticed a while back that there was hardware assisted ECC. This might get in the way of YAFFS ECC but maybe this can be circumvented.
