As a result this memory was not recognized correctly when used with the new spi-fsl-qspi.c driver. >From the dt-bindings: "Required SPI slave node properties: - reg: There are two buses (A and B) with two chip selects each. This encodes to which bus and CS the flash is connected: <0>: Bus A, CS 0 <1>: Bus A, CS 1 <2>: Bus B, CS 0 <3>: Bus B, CS 1" According to above with new driver the second SPI-NOR memory shall have reg=<2> as it is connected to Bus B, CS 0.
