[Sdio-linux-devel] Plug & play option needs to activate?

[boku <bok...@gm...>]

Hi,
    I'm using 2.6.18 and patching the sdio source code. My target is PXA270.
But when I attempt make kernel, it shows errors at compiling the pnp as
follows:
drivers/built-in.o: In function `pnp_check_dma':
drivers/pnp/resource.c:453: undefined reference to `request_dma'
drivers/pnp/resource.c:455: undefined reference to `free_dma'

Do I need to select the pnp if I wanna have a p&p sdio device no matter it's
memory device or sdio device?
Thanks!~

Regards,
boku
