[U-Boot] [PATCH] STx AMC8548: initial support for Silicon Turnkey Express AMC8548 board

Thu Jan 27 09:40:44 CET 2011
AMC8548 is a RapidIO development board in AMC form factor, featuring MPC8548E
processor, DDR2 SO-DIMM slot, 16MB of hardwired NAND flash memory, real time
clock and additional serial EEPROM on i2c bus (enabled). USB controller is
available, but not presently enabled.
Additional board information is available at:
http://www.silicontkx.com/AMC8548.htm

This is really a patch repost from Fall, 2009. The board is old and never was
that good, but I still got those running, so I propped up an u-boot config as
well. Nothing fancy here, just a fairly standard config.
