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,

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.
