CHIPSET: AMD CS5536

[Sven Neumann]

Hi,

I am trying to flash a new coreboot image to our hardware, which is a
"PC Engines ALIX 2C.2" board, see http://pcengines.ch/alix2c2.htm

Latest version of flashrom gives me following output, so I am reporting
this to you as requested:

flashrom v0.9.6.1-r1564 on Linux 3.5.2 (i586)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
coreboot table found at 0xf7c1c00.
Found chipset "AMD CS5536". Enabling flash write... OK.
WARNING: unexpected second chipset match: "AMD CS5536"
ignoring, please report lspci and board URL to [e-mail]
with 'CHIPSET: your board name' in the subject line.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

And here's the output from "lspci -v":

As flashrom does not appear to find the flash chip, I am now somewhat
stuck. Any help would be much appreciated.

OK, I forgot to remove the LPC dongle before running flashrom. Now the
chip is found. I do still get the warning about the unexpected second
chipset match though:

flashrom v0.9.6.1-r1564 on Linux 3.5.2 (i586)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
