It's RB1000 RouterBOOT loader. It's derived from U-boot. This loader can 
load elf image and pass physical pointer to the device-tree block in r3.
Vendor did not share any information about hardware and loader. In this 
case I can't change loader to U-Boot.
RouterBOOT loader successfully load Linux image with RB1000 patches.
Linux sources with patches is here - http://sourceforge.net/projects/rb1000-linux/
I create bootinfo and envoronment in e500_init().
