µClinux setup for USBHOST error

Hi all,

In µclinux setup for USB

****************************************************

In kernel menuconfig,

Turn on SCSI device and SCSI disk.

SCSI device support --->

[ ] RAID Transport Class

[*] SCSI device support

[ ] SCSI target support

[*] legacy /proc/scsi/ support

*** SCSI support type (disk, tape, CD-ROM) ***

[*] SCSI disk support

***********************************************

When i do it i have this code error :

drivers/built-in.o(.text+0x28c00): In function `scsi_dma_map':

/home/hayder/nios2-linux/linux-2.6/include/scsi/scsi_cmnd.h:154: undefined reference to `dma_map_sg'

drivers/built-in.o(.text+0x28c48): In function `scsi_dma_unmap':

/home/hayder/nios2-linux/linux-2.6/include/scsi/scsi_cmnd.h:154: undefined reference to `dma_unmap_sg

***********************************************************

it's normal i don't have dma in my design... I have to modify something???

Thanks for all
