i do step by step in accordance with this doucment : https://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:spi_mmc
but after download to my bf561 board ,i can't find /dev/mmcblk0p* in my uclinux. here is boot info:
mmc_spi spi0.6: ASSUMING SPI bus stays unshared!
mmc_spi spi0.6: ASSUMING 3.2-3.4 V slot power
mmc_spi spi0.6: SD/MMC host mmc0, no DMA, no WP, no poweroff

mmc_spi spi0.6: can't change chip-select polarity
and i try to use the spi driver only, but i can't find the /dev/spidev<bus> , so why i can't find any spi dev in folder of /dev?
my uclinux version is 2.6.34 work on bf561.
