[RFT PATCH 0/4] mtd: spi-nor: code refactoring and layering

Hi,

I found a few areas where code should probably be refactored in the spi-nor
driver layering while reviewing drivers recently. I don't have hardware for
some of this, hence the Request For Test.

Potential future patch: push the MTD registration into a spi_nor_*() API. I
would have just merged it into spi_nor_scan() now, but there are occasionally a
few things that drivers want to do before exposing the MTD but after the SPI
NOR probing. Perhaps a bottom-half API, and an optional all-in-one API that
does both, similar to nand_base's nand_scan_ident(), nand_scan_tail(), and
nand_scan()?

Anyway, enough random musings. Happy reviewing/testing.

Brian

  mtd: fsl-quadspi: use automatic spi-nor detection
  mtd: spi-nor: assign mtd->priv in spi_nor_scan()
  mtd: spi-nor: add forward declaration for mtd_info
  mtd: spi-nor: embed struct mtd_info within struct spi_nor
