[U-Boot] [PATCH v1 1/2] Add CPU and other peripheral support
tmarri at apm.com
tmarri at apm.com
Wed Sep 1 04:11:14 CEST 2010
From: Tirumala Marri <tmarri at apm.com>
APM82XXX 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 AHB bus, DDR and
Some common register definitions.
Signed-off-by: Tirumala R Marri <tmarri at apm.com>
---
V1:
* Squash some of the patches.
* add space between "||" and "\".
* Add spaces around operators.
* Unsigned int to u32.
* Add empty line which was removed.
* remove warning "unused variable" in cpu_init.c
