Realtek SPI-NAND controller
Merge series from Chris Packham <chris.packham@alliedtelesis.co.nz>:
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
