It basically follows the fsl,upm-nand model. I can produce a new patch to ndfc.c for this: [EMAIL PROTECTED],0 { compatible = "amcc,ndfc"; reg = <0x00000001 0x00000000 0x00002000>; ccr = <0x00001000>; bank-settings = <0x80002222>; #address-cells = <1>; #size-cells = <1>; nand { #address-cells = <1>; #size-cells = <1>; [EMAIL PROTECTED] { label = "kernel"; reg = <0x00000000 0x00200000>; }; [EMAIL PROTECTED] { label = "root"; reg = <0x00200000 0x03E00000>; }; [EMAIL PROTECTED] { label = "persistent"; reg = <0x04000000 0x04000000>; }; [EMAIL PROTECTED] { label = "persistent1"; reg = <0x08000000 0x04000000>; }; [EMAIL PROTECTED] { label = "persistent2"; reg = <0x0C000000 0x04000000>; }; }; }; Here is the boot output for both the NOR and the NAND (just for comparison): ffc00000.nor: Found 1 x16 devices at 0x0 in 16-bit bank Amd/Fujitsu Extended Query Table at 0x0040 ffc00000.nor: CFI does not contain boot bank location.
