undefined reference to `tx4925_read_nfmc'

undefined reference to `tx4925_read_nfmc'

[Jason Chen]

Hello sir/madam;

I'am working on Toshiba TX4925 board with Linux 2.4.22 and I want to use
jffs2 on NAND flash. I have run the mtd patch on my kernel, but now my
kernel doesn't compile anymore, the error message is:

drivers/mtd/mtdlink.o: In function `tx4925ndfmc_readecc':

make: *** [vmlinux] Error 1

Please help,

Thanks in advance.

This function is a macro / inline and not part of the mtd subsystem. 

#include <asm/tx4925/tx4925_nand.h>

should contain this.

There are no "tx4925_nand.h" in my kernel source. I use "tx4925.h" 
instead of it, but it seems to lack something. Please kindly tell me 
where can I find it?

Thanks in advance.

This file is not part of the mtd subsystem.

Ask mvista / toshiba or contact the driver author. Alice will have it around
