AMCC NAND controller driver in 2.6.17

[Ramesh]

Hi,
I am using the AMCC PPC 440-EPX board and linux 2.6.17 kernel. The
driver for the built-in NAND controller seems to be the file
sequoia_nand.c. Has anyone seen this working? I am not sure it
programs the EBC registers correctly. Is there a working version of a
driver for the NAND controller? I see ndfc.c in 2.6.19 kernel but I
can't switch kernels yet. Any help is appreciated.

Thanks.
