Subject: [PATCH 05/13 v4] ARM: OMAP3: Add lowlevel init and sys_info common files
From: Dirk Behme <dirk.behme at gmail.com>
Add assembly lowlevel init and sys_info common files
Signed-off-by: Dirk Behme <dirk.behme at gmail.com>
---
Changes in version v3:
- Add detection and support for 128MB/256MB RAM by Mans Rullgard
Changes in version v2:
- Move common ARM Cortex A8 code to cpu/arm_cortexa8/ and OMAP3 SoC specific common code to cpu/arm_cortexa8/omap3 as proposed by Wolfgang.
