I can't recall exactly, but I probably put it there because it seemed 
like it ought to live with the rest of its SoC brethren, or it was 
easier. I think my first version did live in with mtd. It doesn't matter 
to me where it lives. Where does its cousin S3C2410 NAND driver live?

Write support is there, but I haven't had the courage to try it out. :-) 
There is a write_enable module_param for shamcop_nand, which if set to 1 
would theoretically allow writes (which amounts to just setting the 
write enable bit).

Now that you're all set up with JTAG, you seem like the best person to 
try it out. :-)
