Similar to the other ones, different size. The "JV" suffix is in
the datasheet, I haven't seen mentions of a different one.

The the datasheet indicates DUAL and QUAD are supported.

The datasheet says W25M512 not W25Q512.
                      ^-----------^-------- different letter here.

Page 23 mentions the "Q" version which is what we have.

So the M means "Multiple Q dies on single package" ? Why don't you use
w25m in the patch then ?

Because I messed up :-) I got confused between "Q256" and "M512"...

The ID for a single W25Q256JV 0x184019 which we already have
The ID for the dual W25Q256JV aka W25M512JV is 0x187119

Sorry for the mess.

Joel, can you respin ? I don't have my stuff at hand and I'm flying out
tomorrow.

Thanks !

Cheers,
Ben.
