Can not choose the " Specific CFI Flash geometry selection" opition

Hi,

    I use kernel 2.4.2 and the lastest code ,but can not choose the " Specific CFI Flash geometry selection" opition ,please give me some advice?
    
________________________________________________________________________________

cfi_probe.c: In function `cfi_probe_new_chip':
cfi_probe.c:250: `CFIDEV_INTERLEAVE_1' undeclared (first use in this function)
cfi_probe.c:250: (Each undeclared identifier is reported only once
cfi_probe.c:250: for each function it appears in.)

You appear to have enabled a buswidth of 1, but not enabled an interleave 
of 1. This doesn't seem very useful - it's difficult to interleave more 
than one chip into a bus which is a single byte wide.

We should probably do Config.in magic to prevent this. Either that or 
something like...

+#endif
 	case CFIDEV_BUSWIDTH_1:
 		cfi->interleave = CFIDEV_INTERLEAVE_1;
 		cfi->device_type = CFI_DEVICETYPE_X8;

(PS. Please fix your From address)
