This series adds support for the SPI-NAND flash controller on the RTL9300
family of SoCs.

There are 2 physical chip selects which are called SPI_MST_CS0 and SPI_MST_CS1
in the datasheet. Via some pin-strapping these can be assigned to either the
SPI-NOR controller or the SPI-NAND controller. Which means you can end up with
the following permutations

  SPI-Flash
  Boot Model SPI_MST_CS0 SPI_MST_CS1
  ---------- ----------- -----------
  NOR x1     NOR-CS0     X
  NOR x2     NOR-CS0     NOR-CS1
  NAND x1    NAND-CS0    X
  NAND x2    NAND-CS0    NAND-CS1
  NOR+NAND   NOR-CS0     NAND-CS0

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
