[RFC PATCH 0/3] mtd: spi-nor: Rework flash parameter initialization

[Michael Walle]

Try to simplify the flash initialization and get rid of the legacy
handling. As default, all the flags of the in-kernel database are
taken and amended with the SFDP data.

This might have the consequence that all the flashes now get a
RDSFPD opcode which might be an unknown opcode. But that was already
the case for any flashes which were unknown to the linux kernel. So
far, there was not a single complaint.

See patch 3 for more information. If feedback is positive, this is
intended to be applied to the spi-nor tree after the next merge
window, so it will sit around in -next for quite some time and get
some testing.

That being said, I've just did a quick test on my boards. Please
give it a test on your boards.
