Building at91_nand.c for 2.6.15

[Brian Stafford]

Hi

I'm trying to build a 2.6.15.3 kernel for the AT91RM9200 patched with 
current mtd from CVS and 2.6.15-at91.patch.gz (in that order), however 
compilation fails on at91_nand.c because struct at91_nand_data is not 
defined.  I would have expected the declaration of this struct to be in 
one of the at91 header files but I cannot find it mentioned in any other 
source files.  Any idea where I should be looking?

Thanks
Brian
