From: Alex Dubov oakad@yahoo.com
This board, intended for RapidIO development, has following features: * RapidIO interface to backplane * No PCI * USB controller on LBC (not currently enabled) * 16MiB Spansion flash * one soDIMM DDR2 slot
Environment is set to its own, smaller eraseblock near the end of FLASH chip.
