I applied this patch properly, but had no idea it had a dependency as
you didn't mention it in the patch.  Applying "export SPI functions to
standalone apps" resolved the build issue (after moving atmel_df_pow2.c
to its proper location).

Still, why not make this file's compilation dependent on some define
like CONFIG_ATMEL_DATAFLASH_SPI (or whatever is appropriate) when you
resubmit?  I have no interest in compiling it for any boards I use...
