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.
By default the BSP creates an image file for use when loaded into the
RAM of the evaluation board. To create an image file to boot from flash
add the following command to the applications Makefile:
LDFLAGS += -qnolinkcmds -T linkcmdsflash
Note: This BSP has also been tested with the Freescale / Axiom Manufacturing
(M5235BCC Business Card Controller) evaluation board.
ACKNOWLEDGEMENTS:
=================
This BSP is heavily based on the work of:
D. Peter Siddons
Brett Swimley
Jay Monkman
Eric Norum
Mike Bertosh
