Hello Marcin,

thanks for your patch!
Can you please give us a bit of background information? AFAIK the
datasheets of this chipset were never public. Did you RE it for a
specific board? (then why is there no report on that? :) I also wonder
if we should check that the write in enable_flash_nvidia_nforce sticks
and return with an error otherwise?
