- set CONFIG_SYS_I2C_ZYNQ_SPEED for speed setting
- set CONFIG_SYS_I2C_ZYNQ_SLAVE for slave addr
- drivers/i2c/s3c24x0_i2c.c:
- activate this driver with CONFIG_SYS_I2C_S3C24X0
- This driver adds i2c buses (11 for Exynos5250, Exynos5420
9 i2c buses for Exynos4 and 1 for S3C24X0 SoCs from Samsung)
with a fix speed from 100000 and the slave addr 0!
