I've added some more debugging printout and I see that the EECD register contains 0x200 in the error case and 0x300 if everything is working.
So either the NVM cannot be accessed or reading the signature failed.

I've checked the GbE part of my SPI Flash and the Shared Init Control Word (word offset 0x13) in the first part has bits 15:14 set to 10, i.e. a valid signature.

Are these two documents valid for my hardware?
