Please put the flash in atmel.c. There are all the Atmel/Adesto/now Renesas
flashes.

I suppose this flash supports SFDP. Therefore,
{ "at25ql128a", PARSE_SFDP },
should be enough.
I see that the 0x1f42xx IDs are also used for the at25sl series.
Could you shed some light to what the differences are? Are they
compatible, do we have to distiguish between them?
Last, for a new flash submission we require a SFDP dump. See [1].

Did you test locking?
