VIA VT6421A (HZ-006)

[Roy]

Hi all,

It has "HZ-006" printed on the PCB. It does have Pm39LV512-70JCB on the  
board, but it seems no firmware written and no boot ROM messages.

Hello Roy,

thanks for your report! I am collecting some facts about existing cards
in our wiki: http://flashrom.org/VT6421A
I have added the ones I know about your card and would like to add the
remaining ones...

I am not entirely sure what happens there. Obviously pcidev_readbar
reads 0... but we are not using that anyway and don't abort in that
case AFAICS. There has been some discussion about refactor these parts
and that would at least get rid of that message. I'll have to
investigate and discuss this with my colleagues.
What happens after that? flashrom exits?
Can you please add -VVV to the command line and resend the resulting
log?

Ah, I missed an obvious exit call... attached hack should get you
further. If it does not work out of the box you can try the offset
parameter with different values where the n upper bits are all 1 and
everything below that is 0, e.g. for n=12 -p atavia:offset=0xfff00000
Please resend a -VVV log.

The patch is not working for me, pcidev_dev in atavia_init() is NULL here.
