You're running out of memory, somehow only 4MB get recognized: 

Memory available: 4260k/3847k RAM, 0k/0k ROM (1098k kernel code, 2748k data

this menas only about 400kB are available for userspace etc. which is way to small. I guess even 8MB will probably be too small, depending on the configuration of your image (kernel and userspace-tools).

What value does DDR2_TOP_SPAN in your generated header file have?
