It's really a bus controller, with NOR, NAND, and general-purpose modes settable per chipselect. The actual NAND driver goes in drivers/mtd/nand, and is apparently in a separate patch (probably due to separate maintenance domains). It's the same situation as arch/powerpc/sysdev/fsl_lbc.c versus drivers/mtd/nand/fsl_elbc_nand.c and drivers/mtd/nand/fsl_upm.c. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
