mtd: spi-nor: add dt support for Everspin MRAMs
The MR25 family doesn't support JEDEC, so they need explicit mentioning in the list of supported spi IDs. This makes it possible to add these using for example: compatible = "everspin,mr25h40"; There was already an entry for mr25h256. Move that one out of the "keep for compatibility" section and put in a new group for Everspin MRAMs. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com>
