# # $Id$ # Description: Motorola MCF5235EVB ============ CPU: MCF5235, 150MHz RAM: 16M ROM: 2M This is a Motorola evaluation board that uses the MCF5235 Coldfire CPU. This board is running at 150MHz scaled from a 25MHz oscillator. ACKNOWLEDGEMENTS: ================= This BSP is heavily based on the work of: D.
