Ilya Yanok
yanok at emcraft.com
Thu Sep 9 23:03:31 CEST 2010
From: Sergei Poselenov <psl at pollux.denx.de>
This patch provides support for the A4M072 board with the following features:
UART
NOR flash
FEC Ethernet
External SRAM
I2C EEPROM
CompactFlash cards on IDE/ATA port
USB Host
PCI initialization
The 7-segment LED indicator is not yet supported.
