[ts-7000] Re: Source code for ts7xxx_nand and sdcard.o

["Andrea Martino" <>]

Hi all,
I am trying to port the NAND driver to the kernel 2.6, I think it's
quite straightforward, since only minor changes occurred in the NAND
support between kernel 2.4 and kernel 2.6.

After some refactoring, I was able to compile the new module, but when
I load it the kernel crashes. I think I can solve this problem, since
all the NAND structures/APIs did not change much, only some fields in
the structs were reorganized.

Are you sure the "right" module is 
linux24/drivers/mtd/nand/ts7250.c and not
linux24/drivers/mtd2k/nand/ts7250.c (the latter one contains
additional information about ECC)

It's strange, the two files look almost the same, except for the
additional EEC code and a more verbose kernel logging. Furthermore,
/mtd/nand/ts7250.c seems newer than /mtd2k/nand/ts7250.c. When I load
the standard kernel, I see in the kernel log the data printed by the
mtd2k module, this confuses me... ?!?

Can someone explain to me the difference between the two modules?
Which one is the one that is actually used and able to see the NAND Flash?

Thanks a lot
Andrea
