Hi Fabrício,

[Followup to [e-mail] please]

some of us are interested in reverse engineering flashrom SPI support
for your chipset. Do you still have that board available?

Did you get any datasheets from Nvidia?

[coreboot] flashrom on MCP73

[Carl-Daniel Hailfinger]

Hi Fabrício,

latest flashrom now has some debug output which should be helpful in
providing SPI support for your MCP73 board.
Could you run "flashrom -V" with flashrom revision 902 (or later) and
send the output to [e-mail]?
Thanks.

Regards,
Carl-Daniel
