[U-Boot] [PATCH 4/4] stx: add support for STx amc8548 board
oakad at yahoo.com
oakad at yahoo.com
Fri Aug 7 07:28:35 CEST 2009
From: Alex Dubov <oakad at 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.
