C1 - Has QPIC NAND, spi 78b5000-> cs0 -> spi_nor C5 - Has QPIC NAND, spi 78b5000-> cs0 -> spi_nor, cs1 -> spi_nand C2 - Has QPIC NAND, spi 78b5000-> cs0 -> spi_nor ( Audio board, yet to be posted for pending audio drivers) C3 - spi 78b5000-> cs0 -> spi_nor So C3 is the board where it is disabled and enabled in the rest. But from a readability point, feels better to touch this only in each board specific file. So will remove this from the common 04.dtsi and move it to each board file.
