Tue Sep 14 09:26:11 EST 2010
From: Tirumala Marri <tmarri at apm.com>
This patch adds CPU, device tree, defconfig and bluestone board
support for APM821xx SoC.
Signed-off-by: Tirumala R Marri <tmarri at apm.com>
---
V1:
* CPU name changed to 464.
* defconfig is created using "make savedefconfig".
V2:
* CPU name changed back to apm821xx for now.
* some white space problem in device tree.
