Thanks, I'll give that a try. I should have clarified "my processor" a little more. It's a Cirrus Logic EP9312 and yes indeed there is a boot rom internal to the processor that does these checks for a signature that I've put in this header. Essentially it's a way for it to determine if there's a valid image in flash to boot from, otherwise it tries to boot from other interfaces.
I certainly didn't want to do a global change to a Makefile for something like this.
Regards, Adam

Your _processor_? I never head something like that. Are you sure it's not another existing boot loader on your system?
Currently I have the header file as a separate file in the root
...
I don't have to run this script every time. Before I go editing a top-level Makefile, I wanted to ask for advice on how I should go About doing this? Anything I can do in my board-specific directory
would
make me feel better.
Me too, and it's actually easier that way. trun your binary header in an object file and edit the linker script for your board to load this object first.
Best regards,
