Hi Yves,
please keep the list in CC so they know what's going on. Thanks.

here is the corresponding dump :

The flash chip doesn't support RDID.

But the chip supports RES.
probe_spi_res: id 0x13 [....] No EEPROM/flash device found.
The big problem is that ~30 chips from different manufacturers with different sizes all have the same RES ID. I will try to cook up a patch checking REMS (which is more accurate).
It seems to bea SPI flash device but I don't want to open my laptop. Any idea?
I will create a patch to improve detection, but that may take a week or so. If you don't hear anything back from me in the next 7 days, please ask me for a status.
