[U-Boot] [PATCH v5 1/2] APM821xx: Add CPU support

27 Sep 2010

From: Tirumala Marri tmarri@apm.com
APM821XX is a new line of SoCs which are derivatives of
PPC44X family of processors. This patch adds support of CPU, cache,
tlb, 32k ocm, bootstraps, PLB and AHB bus.
Signed-off-by: Tirumala R Marri tmarri@apm.com
---
V4:
  * Rebase with Stefan Roese tree
V5:
  * Move CONFIG_SYS_PERIPHERAL_BASE  to apm821xx.h
