The patch adds suupport for the Freescale's mx35pdk board (known as well as mx35_3stack). The board boots from the NOR flash. Following devices are supported: - two ethernet devices (FEC and SMC911x on debug board) - I2C - PMIC (MC13892) via I2C interface - UART - NOR flash (64MB) - NAND flash (2GB) - basic access to mc9sdz60 registers via I2C interface Signed-off-by: Stefano Babic <sbabic@denx.de>
