How to install SD Card and ethernet at uClinux

Hi, I am trying to get the SD Card mount and have my mmc/spi [*], but I am not seeing the follow boot up message

mmc_spi spi2.0: assuming spi bus stays unshared!

mmc_spi spi2.0: assuming 3.2-3.4 v slot power

mmc_spi spi2.0: sd/mmc host mmc0, no dma, no wp, no poweroff

My next question would be on my pin mapping. Is this pin map correct for the spi 3 wire??

SD_DAT[0] --> MISO

SD_CMD <-- MOSI

SD_CLK <-- SCLK

SD_DAT[3] <-- SS_N

I tried to mount it with no luck

/> mount -t vfat /dev/mmcblk0p1 /mnt

mount: mounting /dev/mmcblk0p1 on /mnt failed: No such device or address

I read post to add the follow lines into the top level design. I tried to add them but compiled with errors, so I am not sure what I have to do, and if anyone know, please kindly let me know.

.MISO_to_the_mmc_spi (SD_DAT),

.MOSI_from_the_mmc_spi (SD_CMD),

.SCLK_from_the_mmc_spi (SD_CLK),

.SS_n_from_the_mmc_spi (SD_DAT3)

Thanks in advance for any help I get from anyone.
