Except for some customers which must maintain kernels during many years :-)

That's the problem i am facing with.

Not a diff but

1) in Linux 2.4.32, I have the following files :
Config.in        diskonchip.c  nand_bbt.c        rtc_from4.c  tx4925ndfmc.c
Makefile         edb7312.c     nand_ecc.c        s3c2410.c    tx4938ndfmc.c
Makefile.common  h1910.c       nand_ids.c        sharpsl.c*
au1550nd.c       nand.c        nandsim.c         spia.c
autcpu12.c       nand_base.c   ppchameleonevb.c  toto.c

2) in Linux 2.4.32, I just have the following files :
autcpu12.c  edb7312.c  nand.c      nand_ids.c
Config.in   Makefile   nand_ecc.c  spia.c
with a very old nand_ids.c.

OK

Yes, I saw  that many things have changed and are not be easily backported.
I checked the MTD CVS. All that I found are in the Linux kernel 2.4.31 or
2.6.x.

Thanks but, I retreived the same files than in the other kernels.


Thanks again for your ideas
I will see what I can do
