Hi Carl-Daniel,

I still have troubles with the detection of my SPI flash.
Here is the result of the dump:

===
  Probing disabled for Winbond W29EE011 because the probing sequence puts the
  AMIC A49LF040A in a funky state.
  Use 'flashrom -c W29EE011' if you have a board with this chip.

No EEPROM/flash device found.
If you know which flash chip you have, and if this version of flashrom
supports a similar flash chip, you can try to force read your chip. Run:
flashrom -f -r -c similar_supported_flash_chip filename

Note: flashrom can never write when the flash chip isn't found automatically.

I don't known if you have enough time to create your patch.
Thanks for your help.
Regards,

Yves
