[U-Boot] [PATCH 1/3 v3] ppc4xx: Add AMCC Arches board support (dual 460GT)
Adam Graham
agraham at amcc.com
Fri Oct 3 00:17:47 CEST 2008
The Arches Evaluation board is based on the AMCC 460GT SoC chip. This board is a dual processor board with each processor providing independent resources for Rapid IO, Gigabit Ethernet, and serial communications. Each 460GT has it's own 512MB DDR2 memory, 32MB NOR FLASH, UART, EEPROM and temperature sensor, along with a shared debug port. The two 460GT's will communicate with each other via shared memory, Gigabit Ethernet and x1 PCI-Express.

v2:
- Added Arches (460GT) support to the existing Canyonlands (460) board
files since the Canyonlands board files support all current AMCC
PPC460EX/GT boards.
v3:
- Correct tab/spaces in canyonlands.h file.
