Please specify which flash chips you are using. The snipped logs are extremely misleading, especially because the RDID output contradicts the MX25L4005 claim in the mail subject. The RDID you are seeing is from a Pm25LV040 (7f 9d 7e).
We need to know the exact flash chip types before we can proceed.
Sorry for length of this
No problem, we are used to even bigger mails. And in your case, I explicitly requested it. Thanks.
Coreboot-v2 release 3088. This is the factory chip, I think
OK. Any chance to find out what's written on the factory chip?

The RDID results are consistent between RDID calls.
Switch up, this is the chip that Harald sent me, the packet has MX25L4005A written on it
OK. Strange... I believe you, but the results below suggest another chip.

EDIT: I just saw your mail from a few minutes ago. The output of the patched flashrom will prove enlightening.
