Dear Gary Thomas,
I have modified the files as given below..
romram.h

extern unsigned long SDRAMSize;
#define CYGMEM_REGION_ram (0)

extern char CYG_LABEL_NAME (_heap1) [];
#define CYGMEM_SECTION_heap1 (CYG_LABEL_NAME (_heap1))

The current files (as provided by Cirrus) only map 16MB for FLASH.
You'll need to make adjustments in 3 places to handle your 64MB device.
