You can't rely on that sort of thing staying at the same address...
check System.map to see where it is now.

Below, you seem to be assuming flash is CS0 and CS3, and that CS1 is BCSR.

Model/compatible should be for the board, not the chip.

BCSR is board-specific, not chip-specific. The compatible should
reference the specific board's name (with the board vendor replacing fsl).

The unit address provides uniqueness; just do "[EMAIL PROTECTED],0".

Note that this should be cfi-flash if your flash is CFI-compatible.

These are specified in bytes, not bits or chips.
I'm guessing you should set them both to 4 based on the above.

The 8272 references should be 8248, though it doesn't currently matt

This doesn't look right...
You'll need to update reg, interrupts, and fsl,cpm-command for whichever
SMC port you're using.
This is for SMC1 on the ep8248e:
[EMAIL PROTECTED] {
device_type = "serial";
compatible = "fsl,mpc8248-smc-uart",
"fsl,cpm2-smc-uart";
reg = <11a80 20 1100 40>;
interrupts = <4 8>;
interrupt-parent = <&PIC>;
fsl,cpm-brg = <7>;
fsl,cpm-command = <1d000000>;
};
Note that the 1100 in reg should be set to wherever your firmware
locates the SMC's parameter RAM block, and fsl,cpm-brg should be set to
whichever BRG your firmware and/or platform code set the SMC port to.

Does your board do mdio the same way as the mpc8272ads board? if not,
you'll have to change this.
