How can I Eliminate BOOT ROM from EPCS Controller

I have a design that is presently booting from EPCS via the Boot ROM. I would like to change this to boot/start from (onchip) RAM.

As part of this change, I really would like to regain the 1K block of memory that is not the unused BOOT ROM.

Is there a way to tell SOPC Builder or Quartus to eliminate the Boot ROM?

Or is my only option to create my own custom version of the EPCS controller?

TIA,

-dave

    AFAIK the EPCS controller without the bootloader is just a regular SPI master. You could just put an SPI master, and then you just have to convince the system to install the EPCS driver anyway, or copy them yourself.
