I was really surprised to see that MPC870 processor, it's a dinosaur!
PowerPC core, 133 MHz core / 66 MHz SDRAM memory (no DDR capability), and the internal peripheral set is designed for networking and communications. If you wanted to build a product with a couple of 10/100M Ethernet ports and an RS232 interface ten years ago then it was a good choice at the time, but I'm amazed to see it in a relatively new design.
