Add support to show the manufacturer, the partname and JEDEC identifier as well as to dump the SFDP table. Not all flashes list their SFDP table contents in their datasheet. So having that is useful. It might also be helpful in bug reports from users. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Acked-by: Pratyush Yadav <p.yadav@ti.com>
