I have built an embedded linux kernel and filesystem for a s3c6410.
The goal is to access a device from user space app using the system SPI bus drivers.

Q1: How do I find the MAJOR MINOR numbers for the SPI drivers?
Q2: Do I use mknod /dev/spixxxB.C c MAJOR MINOR?
Q3: Can someone explain how this should be done?

A list of spi driver files & dirs is as follows:
./sys/devices/platform/s3c2410-spi.0
./sys/devices/platform/s3c2410-spi.0/uevent
./sys/devices/platform/s3c2410-spi.0/modalias
./sys/devices/platform/s3c2410-spi.0/subsystem
./sys/devices/platform/s3c2410-spi.0/bus

./sys/devices/platform/s3c2410-spi.1
