My application contains several large firmware images for supporting devices which do not need to live in SDRAM at run-time and are just read once when they are transferred to the appropriate device. These firmware images are essentially part of my eCos application and are held as a large table array of bytes.

don't include the firmware images with the application? instead store
them in separate flash partitions or in JFFS2?
