Makefile.am, README, startup/init5235.c, startup/linkcmds, startup/linkcmdsflash, startup/linkcmdsram: Modify to the mcf5235 eval boards to either load and run from ram using the dBug moniter as the boot deviced (Board setup as shipped from the factory), or it allows the user to Boot his code from flash he loads onto the eval board. The code changes between the two are based on the selected linker script using a variable in the script. The options to the linker are used to override the default linker script and select which options to configure at boot either from flash, or from ram:

-qnolinkcmds -T linkcmdsflash

If no options are given the standard linker sript assumes dBug was
used to set up the board and the user is going to load his program
to RAM.

Property mode set to 100644

5	Description: Motorola MCF5235EVB
6	============
7	CPU: MCF5235, 150MHz
8	RAM: 16M
9	ROM: 2M
10
11	This is a Motorola evaluation board that uses the MCF5235 Coldfire CPU.
12	This board is running at 150MHz scaled from a 25MHz oscillator.
13
14	By default the BSP creates an image file for use when loaded into the
15	RAM of the evaluation board. To create an image file to boot from flash
16	add the following command to the applications Makefile:
17	LDFLAGS += -qnolinkcmds -T linkcmdsflash
18
19	Note: This BSP has also been tested with the Freescale / Axiom Manufacturing
20	(M5235BCC Business Card Controller) evaluation board.
