[PATCH v2 4/4] mtd: spi-nor: Add support for w25q256jw

[Manivannan Sadhasivam]

Add MTD support for w25q256jw SPI NOR chip from Winbond. This chip
supports dual/quad I/O mode with 512 blocks of memory organized in
64KB sectors. In addition to this, there is also small 4KB sectors
available for flexibility. The device has been validated using Thor96
board.

Can we keep Darshak's authorship? We usually change the author if we feel that
we made a significant change to what was originally published.

If it's just about cosmetics, cleaning or rebase, you can specify what you did
after the author's S-o-b tag and then add your S-o-b, as you did above.

The patch looks good.

Cheers,
ta

I'd suggest to keep Darshak's authorship since he did the actual change in
the bsp. I have to clean it up before submitting upstream and I mentioned
the same above.

Ah no. I was saying we should keep both of ours authorship. It shouldn't
be an issue because we both are involved in the process.

There can be only one author in a patch, and multiple signers if needed:

Please read

or you want to keep yours.

Just keep me as the author of this patch. Darshak still gets credit with his
signed-off-by tag.

Sorry for the confusion!
